Answer:

Diameter of a hemisphere: d = 2 * r ,

Volume of a hemisphere: V = 2/3 * π * r³ ,

Base surface area of a hemisphere: Ab = π * r² ,

Cap surface area of a hemisphere: Ac = 2 * π * r² ,

Total surface area of a hemisphere: A = 3 * π * r² ,

We know that for a hemisphere whose radius is 9 units, The volume is: Volume of hemisphere=2πr33 Volume of hemisphere = 2 π r 3 3
