# Surface Area of a Hemisphere

Â

Curved surface area of a hemisphere = 2p r2 cm2.

Total surface area of a hemisphere = 3
p r2 cm2.
Â

Example:

Find the radius of a hemispherical bowl whose curved surface area is 2p cm2.
Â

Solution:

Curved surface area of a hemisphere = 2pr2cm2.

2
p r2 = 2p

r = 1 cm

The radius of the hemisphere is 1 cm.
