Question
Circumference of one of the bases of a right circular
cylinder is 132 cm. If height of the cylinder is 0.1 metres, then find the volume (in cm3 ) of the cylinder. (Use π = 22/7)Solution
ATQ, Circumference of base of cylinder = 2 X π X radius So, 2 X (22/7) X radius = 132 Or, radius = 132 X (7/44) = 21 cm Height of cylinder = 0.1 X 100 = 10 cm Volume of cylinder = π X radius 2 X height = (22/7) X 212 X 10 = 13,860 cm3
