Question
Circumference of one of the bases of a right circular cylinder is 88
cm. If height of the cylinder is 7 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 = 88 Or,
radius = 14 cm Height of the cylinder = 14 + 7 = 21 cm Therefore,
Volume of cylinder = π × radius² × height = (22/7) × 14² × 21
= 12,936 cm³
