Given:
Radius of the cylinder = 2 cm
Height of the cylinder = 3 cm
To find:
The surface area of the cylinder.
Solution:
The surface area of a cylinder is:

Where, r is the radius and h is the height of the cylinder.
Putting
, we get



Therefore, the surface area of the cylinder is 62.8 square cm.
42 because it is all of the sides have to be added up for the perimeter so the formula would be 14+14+7+7.
