Question

Find the volume of a sphere whose radius is = 0.63

Answer 1

Radius = 0.63 unit

Volume of a sphere = (4/3) π r^3

= (4/3) × (22/7) × (63×63×63)/1000000

= 11 × 9 × 21 × 63 / 500000

= 104781.6/100000

= 1.047816 unit cube.

Answer 2

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

Find the volume of a sphere whose radius is 0.63m

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

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

• Radius of the sphere, r = 0.63m

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

• Volume of the sphere = ❓

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

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

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

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

= 1.0478 m3

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