Question

find the volume of a sphere whose radius is 7cm

Answer 1

radius of the sphere=7cm

volume of the sphere=4πr∧3/3

=4×22×7×7×7/3×7

=4×22×7×7/3

=88×49/3

=4312/3

=1437.34

∴volume of sphere=1437.34cm∧3

Answer 2

Hi there !

_______________________

Radius of sphere = 7cm.

Volume of sphere = 4 / 3 π r³

$\implies{ \mathsf{ \frac{4}{3} \: \pi \: r {}^{3} }} \\ \\ \implies{ \mathsf{ \frac{4}{3} \times \frac{22}{7} \times 7 \times 7 \times 7 }} \\ \\ \implies{ \mathsf{ \frac{4312}{3} }} \\ \\ \therefore{ \mathsf{ 1437\frac{1}{3} }}$
