The surface area of a cylinder can be calculated using the formula:
Surface Area = 2πr(r + h), where r is the radius and h is the height.
Given that the diameter is 24 inches, the radius is half of that, which is 12 inches.
Plugging in the values:
Surface Area = 2 * 3.14 * 12(12 + 48)
Surface Area = 2 * 3.14 * 12 * 60
Surface Area = 2 * 3.14 * 720
Surface Area = 4521.6 square inches
Therefore, the surface area of the rain barrel is 4521.6 square inches.
Joseph has a rain barrel in the shape of a cylinder with a height of 48 inches and a diameter of 24 inches. What is the surface area of the rain barrel? Use 3.14 for π and round to the nearest tenth.(1 point)
