The radius of a hemisphere is 14 cm. Its curved surface area (in cm2) will be: (Use π = 22/7)
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 1232
Given that
The radius of a hemisphere is r = 14 cm
Formuala used
The curved surface area of the hemisphere = 2πr2
Calculation
CSA = 2 × (22/7) × 142
CSA = 1232 cm2
