A cylinder and a hemisphere have the same radius. If the curved surface area of the hemisphere is 128 square centimeters, find the area of the base of the cylinder.
Show answer & explanation
Correct answer: A
Explanation
Curved surface area of hemisphere = 128 cm²
Curved surface area of hemisphere = 2πr²
Area of the base of the cylinder = πr²
2πr² = 128
πr² = 64 cm²
