Question

Find the volume of sphere whose radius is 0.63m.

Answer 1

$the \: volume \: of \: a \: sphere = \\ \\ \frac{4}{3} \pi \: r {}^{3}$

$= \frac{4}{3} \times \frac{22}{7} \times 0.63 \times 0.63 \times 0.63$

$= 1.0478 \: \: m {}^{3}$

Find the volume of a sphere whose radius is 0.63m

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

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

• Radius of the sphere, r = 0.63m

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

• Volume of the sphere = ❓

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

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

= $\frac{4}{3}$× $\frac{22}{7}$× 0.63 × 0.63 × 0.63

= $\frac{4}{3}$× $\frac{22}{7}$× $\frac{63 }{100}$ × $\frac{63 }{100}$× $\frac{63 }{100}$

= 1.0478 m3

$\pink{\underline\bold{ ∴ \:The\:required\:answer\:is\:1.78\: m3}}$
