Question
If the volume of a cylinder is 144π and the ratio of
radius to its height is 3:2 then find the curved surface area of cylinder?Solution
Volume of cylinder = 144π ⇒ πr2h = 144π ⇒ r2h = 144 units ⇒ 9x2*4x = 144 units ⇒ x3 = 8 ⇒ x = 2 Radius = 6 units & height = 4 units. Curved surface area = 2πrh Curved surface area = 48π unit ²
