Question

it the radius of sphere is 2.1cm then find the volume of sphere? ​

Answer 1

Radius of sphere = 2.1 cm

Volume of sphere = 4/3 pi r^2

                              = 4/3 X 22/7 X 2.1 X 2.1

                              = 4 X 22 X 0.7 X 0.3

                              = 18.48 cubic cm
