Question

Which of the following formula would find the surface area of the right cylinder where h is the height?

Answer 1

The surface area formula of a cylinder is :

$SA=2\pi r^2+2\pi rh$

The base area is 2πr^2

and the lateral area is 2πrh

So we can also represent the surface area as :

SA = BA + LA

The answers are A and E
