The curved surface area of a hemisphere is 1232 cm2 . Its radius will be: (Take $π = \frac{22}{7})$
Answer & explanation
Correct answer: option 2
We know that,
Curved surface area of hemisphere = 2πr2
Given,
Curved surface area of hemisphere = 1232 cm2
According to the formula,
2πr2 = 1232
2 × \(\frac{22}{7}\) × r2 = 1232
= r2 = 196
= r = 14 cm
