shape, called spheres.

l Sphere : A sphere is a three dimensional figure, which is made up of all points

in the space, which is at a constant distance from a fixed point. This fixed point

is called centre.

Instructions :

1. Refer page 235 and 237 for understanding the surface area of sphere and

volume of the sphere.
