The formula for finding the surface area of a cylinder is:
Surface Area = 2πr(h + r)
Given that the height (h) is 8 inches and the radius (r) is 7 inches, we can substitute these values into the formula:
Surface Area = 2π(7)(8 + 7)
Surface Area = 2π(7)(15)
Surface Area = 2π(105)
Surface Area ≈ 660.2 square inches
Therefore, the surface area of the cylinder is approximately 660.2 square inches.
Surface Area = 2πr(h + r)
Given that the height (h) is 8 inches and the radius (r) is 7 inches, we can substitute these values into the formula:
Surface Area = 2π(7)(8 + 7)
Surface Area = 2π(7)(15)
Surface Area = 2π(105)
Surface Area ≈ 660.2 square inches
Therefore, the surface area of the cylinder is approximately 660.2 square inches.

I apologize for the mistake. Let's recalculate the surface area of the cylinder.
The formula for the surface area of a cylinder is:
Surface Area = 2πrh + 2πr^2
Given that the height (h) is 8 inches and the radius (r) is 7 inches, we can substitute these values into the formula:
Surface Area = 2π(7)(8) + 2π(7)^2
Surface Area = 2π(56) + 2π(49)
Surface Area = 112π + 98π
Surface Area = 210π
Now, we can approximate the value by using 3.14 as an approximation for π:
Surface Area ≈ 210 * 3.14
Surface Area ≈ 659.4 square inches
Therefore, the correct surface area of the cylinder with a height of 8 inches and a radius of 7 inches is approximately 659.4 square inches.
