What is the total surface area (in sq. cm) of a hemisphere whose curved surface area is 536 cm2?

What is the total surface area (in sq. cm) of a hemisphere whose curved surface area is 536 cm2? Correct Answer 804

Given, Curved surface area = 536 cm2 Let the radius = r Curved surface area / total surface area = 2 πr2 / 3 πr2 ➩ 536 / total surface area = 2 / 3 ➩ 536 * 3 / 2 = total surface area ➩ Total surface area = 804 cm2.
