Find the total surface area of a hemisphere and a solid hemisphere each of radius 10 cm. (π = 3.14).

Answer»

Radius of a hemisphere = Radius of a solid hemisphere = 10 cm

Surface area of the hemisphere = 2πr2 

= 2 x 3.14 x (10)2 cm2 

= 628 cm2 

And, surface area of solid hemisphere = 3πr2 

= 3 x 3.14 x (10)2 cm2 

= 942 cm2
