Question
If the curved surface area and the radius of a cylinder
are 880 cm2 and 28 cm, respectively, then find the volume (in cm3) of the cylinder.Solution
Let, height of cylinder be ‘h’ cm Curved area of cylinder = 880 2 × (22/7) × 28 × h = 880 Or, h = 5 cm Volume of cylinder = (22/7) × (28)2 × 5 = 12320 cm3
