Question

The surface area and volume of a sphere are numerically equal. Find the radius of the sphere.

Answer 1

Answer:

Radius of the sphere is 3 units

Step-by-step explanation:

Surface area of sphere $A= 4\pi r^2$

Volume of the sphere $V= \frac{4}{3} \pi r^3$

Given that Surface area and volume are equal

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

Radius of the sphere is 3 units
