Question
The base of a right circular cylinder has a diameter of
28 cm. The height of the cylinder is 4 cm less than its radius. What is the volume of the cylinder?Solution
Radius of the cylinder = diameter ÷ 2 = (28/2) = 14 cm So, height of the cylinder = 14 – 4 = 10 cm Volume of the cylinder = π × radius2 × height = (22/7) × 14 × 14 × 10 = 6160 cm3
