The radius of a base of a right circular cylinder is 14 cm and height is 30 cm find the curved surface area of the cylinder​

= 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

Step-by-step explanation:

base raduis = 14cm

height of the cylinder = 30cm

we need to determine the curved surface area

CSA of a cylinder = 2πrh

(2)(22/7)(14)(30)

(88)(30)

2640cm^2

Step-by-step explanation:

Given that

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

= 2πrh

= 2(π) 14×30

=2×22/7×14×30

=2×22×2×30

=44×2×30

=88×30

= 2640 sq cm.

The curved surface area of the cylinder is 2640 sq cm.
