A cylinder has a radius of 8/π cm and its volume is 448 cm3. What is the height of the cylinder (take π = 22/7)?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 22 cm.
Given,
Radius (r) = 8/π
The volume of the cylinder = 448 cm3
We know,
Volume of cylinder = πr2h
According to the question,
⇒ πr2h = 448
⇒ π × (8/π)2 × h = 448
⇒ (64/22) × 7 × h = 448
⇒ h = 22 cm
