Question

The radius of base of a cylinder is 7 cm and height is 10 cm, then find the curved surface area of this cylinder.

Answer 1

$csa \: of \: cylinder \: = 2 \times \pi \times r \times h \\ 2 \times 22 \div 7 \times 7 \ \times10 \\ 440$

Answer 2

Heya !!

Here is your answer...

Given, r = 7 cm and h = 10 cm

Now,

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

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

$= > 440 \: {cm}^{2}$

Hope it helps...
