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.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. 2000 π cm3.
Base Diameter = 20 cm
Height = Twice the radius
The volume of the cylinder = πr2h
Diameter = 2 × Radius
The radius of the base = 20/2 = 10cm
Height of a cylinder = 2 × 10 = 20 cm
The volume of the cylinder = π(10)2(20) = π(100)(20) = 2000π cm3
