GETS BRAINLIEST AND 50 PTS!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 needs to be painted for a base circle? Use 3.14 for π and round your answer to the nearest tenth. 7.1 square feet 9.4 square feet 18.8 square feet 28.3 square feet
Accepted Solution
A:
If the diameter is 3 feet, then the radius is 1.5 feet. Area of a circle = pi * radius squared or [tex]A = \pi r^{2} [/tex]
A = pi * (1.5)² A = pi * 2.25 A = 3.14 * 2.25 A = 7.065 ≈ 7.1
