Answer:
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
