Question

what is the formula of t.s.a of hemisphere in radius ​

Answer 1

3πr2(Three pie r square)

Step-by-step explanation:

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. TSA = 2πr2 + πr2 = 3πr2.Therefore,TSA of hemisphere =3πr2
