GPT 3.5
The surface area of a cylinder can be calculated using the following formula:
Surface Area = 2πr^2 + 2πrh
Given that the height (h) of the cylinder is 7 yards and the radius (r) is 8 yards, we can substitute these values into the formula:
Surface Area = 2π(8^2) + 2π(8)(7)
Surface Area = 2π(64) + 2π(8)(7)
Surface Area = 128π + 112π
Surface Area = 240π
Approximating π as 3.14, the surface area of the cylinder is:
Surface Area ≈ 240(3.14)
Surface Area ≈ 753.6 square yards.
Surface Area = 2πr^2 + 2πrh
Given that the height (h) of the cylinder is 7 yards and the radius (r) is 8 yards, we can substitute these values into the formula:
Surface Area = 2π(8^2) + 2π(8)(7)
Surface Area = 2π(64) + 2π(8)(7)
Surface Area = 128π + 112π
Surface Area = 240π
Approximating π as 3.14, the surface area of the cylinder is:
Surface Area ≈ 240(3.14)
Surface Area ≈ 753.6 square yards.
