Answer 2

$\huge\rm\underline\purple{Question :-}$

Find the volume of a sphere whose radius is 21 cm.

$\huge\rm\underline\purple{Answer :-}$

$\boxed{ \sf \green{ Given, }}$

• Radius of the sphere, r = 21 cm

$\boxed{ \sf \red{ To\: find, }}$

• Volume of the sphere = ❓

$\green{\underline\bold{We\:know\:that,}}$

$\boxed{ \sf \blue{ Volume\: of\: a\: sphere=\: \frac{4}{3}Πr3}}$

= $\frac{4}{3}$× $\frac{22}{7}$× 21 × 21 × 21

= 38808

$\purple{\underline\bold{ ∴ \:The\:required\:answer\:is\:38808\: cm3}}$
