The radius of a right circular cylinder is four times of its height. If the height of the cylinder is 14 cm, then what is the volume of cylinder?
Answer & explanation
Correct answer: option 3
We know that,
Volume of a cylinder = πR2H
The radius of a right circular cylinder = four times its height.
The height of the cylinder = 14 cm.
Radius of the cylinder = 14 × 4 = 56 cm
According to the concept,
The volume of the cylinder= π × 562 × 14 = 137984 cm3
