If the daimeter of a solid cylinder with lenght 140cm is 8cm , find its curved surface area ,

Given:

Diameter of a solid cylinder = 8cm

Length (height) of cylinder = 140 cm

To find:

The curved surface area of the cylinder.

Solution:

We have,

Diameter = 8cm

Radius =

Height = 140 cm

Curved surface area of a cylinder is

where, r is radius and h is height.

Putting r=4 and h=140 in the above formula, we get

Therefore, the curved surface area of the cylinder is 3520 square cm.
