Question

10. The surface area of a cylinder with radius rand height h is twice the product of r and the

Answer 1

Step-by-step explanation:

The cylinder is a closed figure which consists of two circular ends. If r is the radius and h is the height of the cylinder, then its surface area is given by :

$A=2\pi rh$

or

$A=2\pi \times r\times h$

We also know that, surface area = perimeter×height

So, the surface area of the cylinder is the product of circumference of the circle and height of the cylinder.
