Question

the volume of sphere is 9/2piecm3 then its diameter is

Answer 1

According to given sum,

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

$\frac{4}{3} \pi {r}^{3} = \frac{9}{2} \pi$

$= > {r}^{3} = \frac{9}{2} \times \frac{3}{4}$

$= > {r}^{3} = \frac{27}{8}$

$= > r = \frac{3}{2}$

Diameter = 2×radius

=>2×3/2

=>3cm.
