The seventh grade class is building target areas for a PE activity. The basis for the game will be in a circular shape. The diameter of each circle is 3 feet approximately how many square feet of turf need to be painted for a base circle use 3.14 for it and round your answer to the nearest 10th.
The formula for finding the area of a circle is A = πr², where r is the radius of the circle.
Given that the diameter is 3 feet, the radius would be half of that, which is 1.5 feet.
Plugging in the values, we get:
A = 3.14 x (1.5)²
A = 3.14 x 2.25
A ≈ 7.065 square feet
Therefore, approximately 7.1 square feet of turf need to be painted for the base circle.
