# Find the total surface area of a hemisphere of radius 10 cm. (Use π = 3.14)

**Solution:**

A hemisphere is exactly half of a sphere having one circular surface at the top.

The total surface area of a hemisphere is half of the surface area of a sphere along with the top circular area added to it.

TSA of hemisphere = (4πr^{2})/2 + πr^{2} = 3πr^{2}

The radius of the hemisphere, r = 10cm

Total Surface area = 3πr^{2}

= 3 × 3.14 × 10cm × 10cm

= 942 cm^{2}

The total surface area of the hemisphere is 942 cm^{2}..
