a tire has a radius of 5 feet and a height of 2 feet in order to understand of much paint is needed adrian wants to now the surface area of the out side of the tire round you answer to the nearest tenth
To find the surface area of the outside of the tire, we need to calculate the area of both the circular top and bottom, as well as the area of the curved side.
1. The area of the circular top and bottom:
The formula for the area of a circle is A = πr^2, where r is the radius.
Plugging in the given radius of 5 feet, we have:
A = π * 5^2
A = π * 25
A ≈ 78.54 square feet (rounded to the nearest hundredth)
2. The area of the curved side:
The tire can be visualized as a vertical cylinder, so the area of the curved side is the circumference of the circle (perimeter of the top/bottom) multiplied by the height.
The formula for the circumference of a circle is C = 2πr.
Plugging in the given radius of 5 feet, we have:
C = 2π * 5
C = 10π
The height of the tire is given as 2 feet.
Therefore, the area of the curved side is:
A = C * h
A = 10π * 2
A ≈ 62.83 square feet (rounded to the nearest hundredth)
3. Total surface area of the outside of the tire:
The total surface area is the sum of the areas calculated in steps 1 and 2.
Total Surface Area = Circular Top/Bottom Area + Curved Side Area
Total Surface Area ≈ 78.54 + 62.83
Total Surface Area ≈ 141.37 square feet (rounded to the nearest hundredth)

3. Total surface area of the outside of the tire:
The total surface area is the sum of the areas calculated in steps 1 and 2.
Total Surface Area = Circular Top/Bottom Area + Curved Side Area
Total Surface Area ≈ 78.5 + 62.8
Total Surface Area ≈ 141.3 square feet (rounded to the nearest tenth)
