Find the surface area of the cylinder leave your answer in terms of pie

54π cm²

Step-by-step explanation:

It's pi, or π, but definitely not "pie."

The surface area has two parts:  the vertical side and the two ends.

The formula for the area of the vertical sides is A = πr²h, where r is the radius and h is the height.  Here, we have:

A = π(3 cm)²(5 cm) = 45π cm²

Each of the ends has the following area:  A = πr², or A = 9π cm²

Thus, the total surface area of the cylinder is 45π cm² + 9π cm², or 54π cm²
