What is the total surface area and the curved surface area of a solid hemisphere of radius 14 cm?
Answer & explanation
Correct answer: option 2
We know that,
The total surface area of a solid hemisphere = 3πr2
The curved surface area of a solid hemisphere = 2πr2
We have,
Radius of hemisphere = 14 cm
The total surface area of a solid hemisphere = 3 × \(\frac{22}{7}\) × 142 = 1848 cm2
The curved surface area of a solid hemisphere = 2 × \(\frac{22}{7}\) × 142 = 1232 cm2
