Question

find the volume of a sphere whose radius is 7cm​

Answer 1

Step-by-step explanation:

radius of the sphere= 7cm= r

volume of the sphere= 4/3πr^3

= 4/3 × 22/7 ×7×7×7

=30184/21= 1437.33 cubic. cm

Answer 2

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

Find the volume of a sphere whose radius is 7 cm.

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

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

• Radius of the sphere, r = 7 cm

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

• Volume of the sphere = ❓

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

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

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

= $\frac{4}{3}$× 22 × 7 × 7

= 1436.0 cm3

$\pink{\underline\bold{ ∴ \:The\:required\:answer\:is\:1436.0\: cm3}}$
