Question

the volume and surface area of a sphere is
numerically equal, then the radius of the sphere is ​

Answer 1

Answer:

Radius = 3

Step-by-step explanation:

Volume of a Sphere,

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

Surface Area of sphere,

$S=4\pi r^{2}$

Given that Volume = Surface Area

V = S

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

On simplifying and cancelling the common factors, we get,

r = 3
