To find the surface area of a cylinder, you need to calculate the lateral area and the two circular bases separately.
Lateral area = 2πrh
Lateral area = 2 * π * 15 * 18
Lateral area = 540π cm2
Base area = 2πr2
Base area = 2 * π * 152
Base area = 450π cm2
Total surface area = Lateral area + 2(Base area)
Total surface area = 540π + 450π
Total surface area = 990π cm2
Therefore, the surface area of the cylinder is 990π cm2.
