Find the surface area of a cylinder with a height of 4 yards and a radius of 2 yards. use 3.14 for pi and round to the nearest tenth.
To find the surface area of a cylinder, we need to calculate the sum of the areas of the two bases (top and bottom) and the lateral surface area.
The formula for the surface area of a cylinder is:
Surface Area = 2πr² + 2πrh
Given that the radius (r) is 2 yards and the height (h) is 4 yards, we can substitute these values into the formula to calculate the surface area:
Surface Area = 2 * 3.14 * (2²) + 2 * 3.14 * 2 * 4
Surface Area = 2 * 3.14 * 4 + 2 * 3.14 * 2 * 4
Surface Area = 25.12 + 50.24
Surface Area = 75.36
Therefore, the surface area of the cylinder is 75.36 square yards.
