Question

If the curved surface area of a square is 64 π cm square then its volume will be:
​

Answer 1

Answer:

According to the question,

Total surface area the sphere = 64π cm2

⇒ 4πr2 = 64π

⇒ 4r2 = 64

⇒ r2 = 64/4

⇒ r2 = 16

⇒ r = √16

⇒ r = 4 cm ----(Negative value of radius is not practical
