Find the volume of a cylinder whose diameter of base is 20 cm and height is two times that of the radius of its base.
Answer & explanation
Correct answer: option 2
We know that,
Volume of cylinder = πR2H
The diameter of the cylinder = 20cm
then the radius = 10 cm
Height is two times the radius of base = 20cm
Then =
Volume of cylinder = π × 102 × 20
= Volume of cylinder = 2000π cm3
