The curved surface area and circumference at the base of a solid right circular cylinder are 2200 cm2 and 110 cm, respectively. Find the height of the cylinder.
Answer & explanation
Correct answer: option 3
We know that,
Base of a solid cylinder = 2πr = 110cm
The curved surface area of cylinder = 2200cm2
= 2πrh = 2200
= 110 × h = 2200
= h = 20cm
