Question

if surface area and volume of sphere is equal,find radius

Answer 1

4/3 pie r3 = 4 pie r2
r = 3

Answer 2

Answer:

r=3

Step-by-step explanation:

surface area of sphere = 4 π r²

volume of sphere = 4/3 π r³

surface area = volume of the sphere

4 π r²= 4/3 π r³

4 and π and r² are cancelled

remaining is

r/3=1

r=3
