Question

The volume of the sphere is equal to it's the surface area . Then find the diameter of the sphere

Answer 1

Answer:

diameter=6cm

Step-by-step explanation:

Volume of sphere=

$\frac{4}{3} \pi r {}^{3}$

Surface area of sphere=

$4\pi r {}^{2}$Therefore,

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

$\frac{1}{3} r = 1$

$r = 3cm$

$diameter = 6cm$
