To find the surface area of a cylinder, you can use the formula:
Surface area = 2πr(r + h)
Given that the radius (r) is 12 feet and the height (h) is 20 feet, plug in these values to find the surface area:
Surface area = 2 * π * 12(12 + 20)
Surface area = 2 * π * 12(32)
Surface area = 2 * π * 384
Surface area ≈ 2413 ft2
Therefore, the correct answer is:
2,413 ft2
Use a formula to find the surface area of the cylinder to the nearest whole unit.
The cylinder has a top radius of 12 feet and a height between bases of 20 feet.
