Surface Area of a Cylinder

In real life there are many examples of cylinders like

All cylinders have a base, a top and a curved face.

Learn how to calculate the surface area of a cylinder in this video.

From the images and video viewed earlier:

Surface Area of a cylinder is the Area of top and bottom plus Area of the curved side.

Therefore,

Surface Area = 2(Area of circular top) + (circumference of top) by height of cylinder
