What is the diameter of the hemisphere? Let the radius of the hemisphere be x units. Hence, the diameter of the hemisphere is equal to 9 units.

Volume (Hemisphere)=32πr3

Surface area=3πr2

∴3πr2=32πr3

⇒r=29

⇒2r=9

⇒d=9.

What is the diameter of the hemisphere? Let the radius of the hemisphere be x units. Hence, the diameter of the hemisphere is equal to 9 units.
