The radius of a right circular cylinder is five times of its height. If the height of the cylinder is 3.5 cm, then what is the volume of cylinder?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. 3368.75 cm3.
Given:
Height = 3.5 cm
Radius = 5 × Height
Formula used:
Volume of cylinder = πr2h ---- (1)
Where r = radius and h = height
Calculations:
We know that, Radius = 5 × Height
⇒ radius = 5 × 3.5 = 17.5 cm
Using equation (1), we get
Volume of cylinder = (22/7) × 17.5 × 17.5 × 3.5 = 3368.75 cm3
