Question
If the curved surface area and the radius of a cylinder
are 660 cm2 and 14 cm, respectively, then find the volume (in cm3) of the cylinder.Solution
Let, height of cylinder be ‘h’ cm Curved area of cylinder = 660 2 × (22/7) × 14 × h = 660 Or, h = 7.5 cm Volume of cylinder = (22/7) × (14)2 × 7.5 = 4620 cm3
