Question

a cylinder of height 8cm and perimeter of base is 44cm.find csa

Answer 1

Answer:

curved surface area of cylinder is, 352 cm square

Step-by-step explanation:

Perimeter of base of the cylinder is given by:

$P = 2 \pi r$ where

P is the perimeter of the base of thew cylinder and r is the radius of the cylinder.

Curved surface area of the cylinder is given by:

$\text{CSA} = 2 \pi rh$ ....[1] where h is the height of the cylinder

As per the statement:

a cylinder of height 8 cm and perimeter of base is 44 cm.

⇒ h= 8 cm and P = 44  cm

$\text{CSA} = 2 \pi rh$

or

$\text{CSA} = Ph$      ....[1]

Substitute the given values in [1] we have;

$\text{CSA} = 44 \cdot 8 = 352 cm^2$

Therefore, curved surface area of cylinder is, 352 cm square
