= 2(pi)rh = 2(pi)14*30 = 2640 sq cm. If the radius of a cylinder is doubled keeping its lateral surface the same, then what is its height? The respective ratio of the curved surface area and the total surface area of a cylinder is 9: 16
base raduis = 14cm
height of the cylinder = 30cm
we need to determine the curved surface area
CSA of a cylinder = 2πrh

The radius of a base of a right circular cylinder = 14 cm
The height of a base of a right circular cylinder = 30 cm
To find: The curved surface area of cylinder
The curved surface area of the cylinder= 2πrh
r=radius and h=height
= 2(π) 14×30
= 2640 sq cm.
The curved surface area of the cylinder is 2640 sq cm.
