Question

If the volume and surface area of a sphere is numerically equal. Then its radius is
(a) 2 units
(b) 3 units
(c) 4 units
(d) 5 units​

Answer 1

Answer:

(c). 3 units. this is your answer

Answer 2

Step-by-step explanation:

surface area of sphere = 4πr2

volume of sphere is 4/3 πr3

3r² = r^3.

when volume and surface area is equal then the radius will be 3 units
