Answer 1

V=4/3πr^3

V=4/3*3.14*27

V=113.04cm^3

Answer 2

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

Find the volume of a sphere whose radius is 3 cm.

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

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

• Radius of the sphere, r = 3cm

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

• Volume of the sphere = ❓

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

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

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

= 4 × $\frac{22}{7}$× 3 × 3

= 113.1 cm3

$\pink{\underline\bold{ ∴ \:The\:required\:answer\:is\:113.1\: cm3}}$
