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 surface area of a cylinder is given by the formula:
Surface Area = 2πr(r + h)
First, we need to find the radius of the cylinder, which is half of the diameter. So, the radius (r) is 12 inches.
Now we can plug the values into the formula and solve:
Surface Area = 2(3.14)(12)(12 + 48)
Surface Area = 2(3.14)(12)(60)
Surface Area = 4521.6 square inches
Rounded to the nearest tenth, the surface area of the rain barrel is 4521.6 square inches.
