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) in.2
I apologize for the error in my calculations. Let me correct it.
The surface area of a cylinder is calculated using the formula:
Surface Area = 2πr(r + h), where r is the radius, and h is the height.
Given:
Height (h) = 48 inches
Diameter = 24 inches -> Radius (r) = 12 inches
Surface Area = 2 * 3.14 * 12 (12 + 48)
Surface Area = 2 * 3.14 * 12 * 60
Surface Area = 2 * 3.14 * 720
Surface Area = 4,521.6 square inches
Rounded to the nearest tenth, the surface area of the rain barrel is 4,521.6 in^2.

The surface area of a cylinder is calculated by adding the area of the two circular bases and the lateral surface area.
First, let's calculate the area of the two circular bases:
Radius = diameter/2 = 24/2 = 12 inches
Base area = π*radius^2 = 3.14*12^2 = 452.16 square inches
Now, let's calculate the lateral surface area:
Lateral surface area = height * circumference of the base
Circumference = 2*π*radius = 2*3.14*12 = 75.36 inches
Lateral surface area = 48*75.36 = 3,620.88 square inches
Now, let's total up the surface area:
Total surface area = 2*Base area + Lateral surface area
Total surface area = 2*452.16 + 3,620.88
Total surface area = 904.32 + 3,620.88
Total surface area = 4,525.2 square inches
Rounded to the nearest tenth, the surface area of the rain barrel is 4,525.2 in^2.
