To find the surface area of a cylinder, we need to find the sum of the areas of the two bases and the curved surface area.

The formula for the surface area of a cylinder is:

SA = 2πr² + 2πrh

where r is the radius of the cylinder's base and h is the height of the cylinder.

Using the approximation of 3.14 for pi, we can calculate the surface area.

Let's say the radius of the cylinder is 4 units and the height is 5 units.

First, let's calculate the areas of the two bases:

Base Area = πr² = 3.14 * 4² = 3.14 * 16 = 50.24 square units

Next, let's calculate the curved surface area:

Curved Surface Area = 2πrh = 2 * 3.14 * 4 * 5 = 125.6 square units

Now, let's find the total surface area:

SA = 2πr² + 2πrh = 2 * 3.14 * 16 + 125.6 = 32.96 + 125.6 = 158.56 square units

Therefore, the surface area of the cylinder is approximately 158.56 square units.
