Question

what is the CSA of hemisphere?​

Answer 1

Step-by-step explanation:

The total surface area of a hemisphere = 3πr2 square units

Where π is a constant whose value is equal to 3.14 approximately.

Answer 2

Answer:

CSA = 2πr². The curved surface area of a hemisphere = 2πr2 square units. The total surface area of the sphere = Curved surface area of sphere + base area. We know that the base of the hemisphere is circular in shape, use the area of the circle.
