If the volume of a cylinder is 180π and the ratio of radius to its height is 6:5 then find the curved surface area of cylinder?
Volume of cylinder = 180π ⇒ πr2h = 180π ⇒ r2h = 180 units ⇒ 36x2*5x = 180 units ⇒ x3 = 1 ⇒ x = 1 Radius = 6 units & height = 5 units. Curved surface area = 2πrh Curved surface area = 60π unit ²
