Radius (r) of hemisphere = 10 cm
Total surface area of hemisphere = CSA of hemisphere + Area of circular end of hemisphere
=2πr^2+πr^2
=3πr^2
= [3*3.14*10*10] cm2.
=943cm2.
Therefore, the total surface area of such a hemisphere is 942 cm2.

The surface area of the hemisphere= 2πr^2
= 2×3.14×(10)^2
= 628cm^2
The surface area of solid hemisphere= 3πr^2
= 3×3.14×(10)^2
=942cm^2
= 2×3.14×(10)^2
= 628cm^2
The surface area of solid hemisphere= 3πr^2
= 3×3.14×(10)^2
=942cm^2
