Find the SURFACE AREA AND VOLUME of how much you studied.

It is very well known that this chapter on surface area and volume has a lot of formulas that you need to learn. But before that, it is required to understand what precisely these formulas are finding out.

As the name suggests, the formulas are all about finding the measurements. But have you measured the chances of you getting good marks in the chapters you find difficult in maths? Not yet? Don’t wait, check now!. Take a test on the SeekoG app to know how much you remember from class 9th so that your class 10 becomes easier to understand. This chapter covers much surface area and volume of the syllabus like its name. But nothing to be worried about if you can have a quick revision of all the concepts like:

Surfaces

Especially the Surface Area of Cubes and Cuboids: This consists of calculating and adding the areas of all the faces.

Surface Area of Cylinders: Determining the areas of the two circular bases as well as the curved surface area.

Surface Area of Spheres: Calculating the surface area of spheres.

Similarly, there you will have to calculate volume as well:

Volumes

Cubes and Cuboids Volume: Multiplying the length, width, and height.

The volume of cylinders: Figuring out the product of the base area and the height.

The volume of spheres. This is accomplished by applying the formula (4/3)r3, where r is the radius of the sphere.

After this quick memory jog are you sure you are ready to understand all that your teacher will teach you in Class 10 Mathematics' Surface areas & Volumes? Why don't you make it 100% sure by perfecting your base in Class 9 Surface area & Volumes and make your class 10 Maths a Cakewalk? Take a test now, Get your Gap Analysis Report, fix all the gaps in the chapter & be ready to score 90+ in Class 10 Maths.

When your memory is ready with all the formulas conversion of units will become so easy that you would have never imagined. Confidence is all that is needed for this chapter and now that you are confident enough prove it to yourself!! Take a test on SeekoG and be proud of what you learned and definitely your memory.

Now you know about a sphere which is a 3D figure but what about the 2D version of it? Confident about Triangles? Here's what you need to know.

What is the surface area of a sphere?

There are various geometrical figures that the students often come across. The sphere is one such concept that helps the students to learn and to compute the solutions as well.  

Few of the interesting facts that we all see is:

The geometrical shape of the sphere is always round and this can always be represented in the three dimensional space.

This is often defined as a flat figure as it does not have any sides and is a flat surface.

The volume of the sphere is calculated as 4/3 πr3

The volume of the sphere will always be equal to the surface area of the sphere and will be calculated by the formula 4πr2 

We can see the general representations of the sphere where we assume the distance from the center to the sides of the sphere as “R”.phere The other parameters are calculated based on the values.

Definition

In the geometrical applications, there are different other parameters also that we often see to define the sphere and the geometrical importance. So, a sphere is also defined as a geometrical round shape in three dimensional spaces. The sphere usually does not have any flat surface as we are not being able to define the sphere in terms of dimensions as in the length or breadth.

Unlike circle, that can also be explained in a plane shape or flat shape that is usually being defined in XY plane, in case of the sphere is defined in three dimensions, i.e. x-axis, y-axis and z-axis.

Important Facts:

A sphere is a symmetrical object that has all the dimensions defined in the same plane.

When we calculate the  surface points of sphere they are at equidistant from center

A sphere as a geometrical shape has only curved surface, no flat surface, no edges and no vertices.

Properties of a sphere

The sphere as a geometrical figure has few of the important features. These are also called attributes of sphere.

A sphere is a perfectly symmetrical shape that is represented in a 3D space.

It is not a polyhedron in nature.

All the points marked on the surface will be equidistant from the center.

The sphere does not have a surface of centers and will have a constant mean curvature

In case of the sphere there is a constant value for the width and circumference.

Shape of Sphere

The shape of a sphere is round where it does not have any faces. It should be noted that sphere is a geometrical three dimensional solid that have got curved surface. Like other solids, such as cuboid, cube, cone and cylinder, it does not have any flat surface or a vertex or an edge.

Now let us have a look at the real-life examples of sphere which are:

Basket balls

World Globe

Marbles

Planets

Moon

Equation of a Sphere

In the field of analytical geometry, if “r” is considered the radius, (x, y, and z) is said to be the locus of all points and (x0, y0, z0) is the center of a sphere, and then the equation of a sphere can be written as:

(x -x0)2 + (y – y0)2 + (z-z0)2 = r2

Formulas

As per statistics, the diameter is twice the radius. Therefore, diameter of a sphere is given as:

D = 2r units

Since we know that all the three-dimensional objects have the surface area and the volume, the surface area well as the volume of the sphere is explained so that we will be able to understand the system.

Surface Area of a Sphere

As the sphere is always represented in the 3D space, so a there is a mechanism to calculate the surface area... The formula of surface are is given by:

The Surface Area of a Sphere (SA) = 4πr2 Square units

Where “r” is considered the radius of the sphere.

Volume of a Sphere

This is so very important that we should be able to calculate the volume of the square as well.  This is often being defined as the amount of space occupied by the object three-dimensional object. The volume is to be calculated in many of the mathematical calculations as this will be able to give us the value addition and also the perfect representation on a scheduled space.

So, if we are to apply the Archimedes Principle, the volume of a sphere is given as,

The volume of Sphere (V) = 4/3 πr3 Cubic Units

The concepts are better explained in the online contents by

www.doubtnut.com It provides the latest materials to study along with online video tutorials that will help the students to understand the concept with ease. Moreover, there are doubts clearing sessions that are conducted that helps the students to identify their weakness and also build in the confidence. With their beautifully explained topics, Doubtnut are able to provide the students with the required materials to top up on their concept of learning and building in confidence.
