   How do you find the surface area of a hemisphere?

   • The base of the hemisphere is a flat circular shape. Area of circle = πr 2 Area of the circular base of a hemisphere = πr 2 The total surface area of the hemisphere is defined as the sum of the space occupied by the curved area and the flat surface area (or the base area) of the hemisphere.

   What is the curved surface area of the hemisphere?

   • (i) CSA of the hemisphere= 2 × 3.14 × 4 × 4 CSA = 3.14 × 32 CSA = 100.48 cm 2 (ii) TSA of the hemisphere = 3 × 3.14 × 4 × 4 TSA = 3.14 × 48 TSA = 150.72 cm 2 Therefore, the curved and the total surface area of the hemisphere are 100.48 and 150.72 cm 2, respectively.

   What is the total surface area of hemisphere?

   • 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. We can find various real-life examples of the hemispheres such as our planet Earth can be divided into two segments the southern & northern hemispheres.
