Q13 of 79 Page 245

The total surface area of a solid hemisphere of diameter 2 cm is equal to

Diameter = 2 cm


Radius (r) = 1 cm


Total surface Area = Curved surface Area + Base Area


⇒ Total surface Area = 2πr2 + πr2 = 3πr2


⇒ Total surface Area = 3π × 12 = 3π cm2


Out of all the four Options,
