What will be the difference between total surface area and curved surface area of a hemisphere having 2 cm diameter?
Correct Answer: π sq cm
Explanation:
Given,
Diameter = 2 cm
∴ r = 1 cm
Now, Total surface area of hemisphere = 3πr2
and curved surface area = 2πr2
Required difference = 3πr2 - 2πr2 = πr2
= π x 12 = π sq cm
