Question

If the surface area of a sphere be numerically equal to three times the volumes, then the radius of the sphere will be​

Answer 1

Answer:

3 units

Step-by-step explanation:

Let the radius of the sphere be r Units

So, volume of sphere=4/3 pie r^2

And, surface area of sphere =4πr^2

Given, Volume = surface area

4/3pie r^3=4pie r^2

r=3
