Answer 1

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

Find the volume of a sphere whose radius is 2.1 cm.

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

$\green{\underline\bold{Given,}}$

• Radius of the sphere, r = 2.1 cm

$\red{\underline\bold{To\: find,}}$

• Volume of the sphere = ❓

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

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

= $\frac{4}{3}$× $\frac{22}{7}$× 2.1 × 2.1 × 2.1

= 4 × 22 × 0.1 × 2.1 × 2.2

= 40.65 cm3

$\pink{\underline\bold{ ∴ \:The\:required\:answer\:is\:40.65\: cm3}}$
