Answer 2

Hi there !

_______________________

Diameter of sphere = 21 cm.

Radius of sphere = 21 / 2 cm

Volume of sphere = $\mathsf {\frac {4} {3}}$ π r³

$\mathsf{ \frac{4}{3} \times \frac{22}{7} \times \frac{21} {2} \times \frac{21} {2} \times \frac{21} {2}} \\ \\ \mathsf{11 \times 21 \times 21 } \\ \\ \mathsf{ 4851\: cm {}^{3}}$
