Question

3. The radius of a sphere is 2x, then its volume will be

Answer 1

$Given \: radius \: of \: a\: sphere (r) = 2x$

$\boxed { \pink { Volume \: of \: a\:sphere (V) = \frac{4}{3} \pi r^{3} }}$

$\implies V = \frac{4}{3} \times \pi \times (2x)^{3}\\= \frac{4}{3} \times \pi \times 8x^{3}\\= \frac{32}{3} \pi x^{3} \: cubic \:units$

Therefore.,

$\red { Volume \: of \:the \:Sphere } \green {= \frac{32}{3} \pi x^{3} \: cubic \:units}$
