The formula to find the surface area of a cylinder is:

Surface Area = 2 * pi * radius * (radius + height)

In this case, the radius is 6 inches and the height is 20 inches. Substituting these values into the formula:

Surface Area = 2 * 3.14 * 6 * (6 + 20)
Surface Area = 2 * 3.14 * 6 * 26
Surface Area = 3769.28 square inches

Therefore, the surface area of the cylinder is 3769.28 square inches.

I apologize for the mistake. Let's recalculate the surface area of the cylinder with the correct formula:

Surface Area = 2πrh + 2πr^2

Given that the height (h) is 20 inches and the radius (r) is 6 inches, we can now calculate the surface area:

Surface Area = 2 * 3.14 * 6 * 20 + 2 * 3.14 * 6^2
Surface Area = 2 * 3.14 * 6 * 20 + 2 * 3.14 * 36
Surface Area = 376.8 + 226.08
Surface Area = 602.88 square inches

Therefore, the surface area of the cylinder is 602.88 square inches.

Let's try calculating the surface area again using the correct formula:

Surface Area = 2πr(r + h)

Given that the height (h) is 20 inches and the radius (r) is 6 inches, we can now substitute these values into the formula:

Surface Area = 2 * 3.14 * 6(6 + 20)
Surface Area = 2 * 3.14 * 6(26)
Surface Area = 2 * 3.14 * 156
Surface Area = 2 * 490.64
Surface Area = 981.28 square inches

Therefore, the surface area of the cylinder with a height of 20 inches and a radius of 6 inches is 981.28 square inches.
