Question
Circumference of one of the bases of a right circular
cylinder is 132 cm. If height of the cylinder is 5 cm more than its radius, then find the volume (in cm³) of the cylinder. (Use π = 22/7)Solution
Circumference of base of cylinder = 2 × π × radius So,
2 × (22/7) × radius = 132 Or,
radius = 21 cm Height of the cylinder = 21 + 5 = 26 cm Therefore,
Volume of cylinder = π × radius² × height = (22/7) × 21² × 26
= 36,036 cm³
