Question

A cylinder of height 8cm and perimeter of base is 44cm. Find its curved surface area.

Answer 1

Answer:

Step-by-step explanation:

given;

h=8cm

perimeter of base=44cm

2πr =44

2×22÷7×r = 44

r=7

CSA= 352cm²

Answer 2

Answer:

The curved surface area of the cylinder is 352 centimeter square.

Step-by-step explanation:

Given : A cylinder of height 8cm and perimeter of base is 44cm.

To find : Its curved surface area?

Solution :

The formula of curved surface area of the cylinder is

$CSA=2\pi rh$

Where, h=is the height h=8cm

r is the radius

Perimeter of base= 44cm

$2\pi r=44$

Substitute in the formula,

$CSA=(44)(8)$

$CSA=352cm^2$

Therefore, The curved surface area of the cylinder is 352 centimeter square.
