The seventh-grade class is building target areas for a PE activity. The bases for the game will be in a circular shape. The diameter of each circle is 3 feet. Approximately, how many square feet of the turf need to be painted for a base circle? Use 3.14 for π and round your answer to the nearest tenth. (1 point)
7.1 square feet
9.4 square feet
18.8 square feet
28.3 square feet
The formula to find the area of a circle is A = πr^2, where r is the radius of the circle.
The diameter of each circle is 3 feet, so the radius is half of that, which is 3/2 = 1.5 feet.
Now plug the radius into the formula:
A = 3.14 * (1.5)^2
A = 3.14 * 2.25
A ≈ 7.065
Rounding to the nearest tenth, the approximate area is 7.1 square feet.
Therefore, the answer is 7.1 square feet.
