Question

The diameter of a cylinder is 28 cm and height is 10 cm. How much will be the curved surface area of this cylinder?

Answer 1

CSA of cylinder=2πrh
CSA of cylinder=2*22/7*14*10
CSA of cylinder=880m sq

Answer 2

Heya !!

Here is your answer...

Given, diameter = 28 cm. So radius = 14 cm

Also, h = 10 cm

Now,

$CSA \: of \: cylinder = 2\pi rh$

$= > 2 \times \frac{22}{7} \times 14 \times 10$

$= > 880 \: {cm}^{2}$

Hope it helps..
