Question
The curved surface area of a
right circular cylinder with a radius of 7 cm is 440 cm². If the height of the cylinder is increased by 50%, what will be its volume?Solution
ATQ, Curved surface area of the cylinder = 2 × π × radius × height = 2 × (22/7) × 7 × height = 440 So, height of the cylinder = 440 ÷ 44 = 10 cm Increased height of the cylinder = 10 × 1.5 = 15 cm So, volume of the cylinder = π × radius2 × height = (22/7) × 72 × 15 = 2310 cm3
