Question

The area of base of a hemisphere is 36cm^2. Find its curved surface area

Answer 1

Answer:

Let the radius of the hemisphere be ′r′ cm.

Area of base =36πcm2

⇒πr2=36π

⇒r2=36 

⇒r=6cm

∴  Volume of hemisphere =32πr3

                                            =32×π×6×6×6

                                            =144πcm3
