Answer:
Curved surface area of hemisphere = 1/2 ( 4 π r2) = 2 π r2
Base Area
The base of the hemisphere is in circular shape. As we know by the formula of area of circle,
Area of base = π r2
Total Surface Area
The total surface area of the hemisphere– While calculating the total surface area of a hemisphere, we need to consider the base of the hemisphere which is circular. Thus, the total surface area of a hemisphere is equal to:
Total Surface Area (TSA) = Curved Surface Area + Area of the Base Circle
= 2 π r2 + π r2
= 3 π r2

A hemisphere is obtained when we cut the sphere into two equal halves. The total surface area of hemisphere will be equal to the sum of its curved surface area and the base area of hemisphere. The base is in circular shape here.
