Question

what is the volume of a sphere if radius =0.7cm

Answer 1

Volume of the given sphere= 4/3 x pi x r to the 3
=1.44cmcube

Answer 2

Volume of sphere = $4/3\pi r^{3}$

                              =4/3*22/7*0.7*0.7*0.7

                              =88/3*0.1*0.7*0.7

                              =4.312/3

                              =1.437 cubic centimeters
