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.??
The formula for the surface area of a cylinder is 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.
Now, plug in the values:
Surface area = 2 * 3.14 * 12(12+48)
Surface area = 2 * 3.14 * 12 * 60
Surface area = 7539.84 square inches
Therefore, the surface area of the rain barrel is approximately 7539.8 square inches.
