The seventh-grade class is building target areas for a PE activity. The bases for the game will be in a circular shape. The diam
eter 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.
The base is made of a circular shape, so to solve this question we need to know how to calculate the circle area. The formula for the circle area is π * r^2 so we need to find the radius(r). Radius equal to half of the diameter and the diameter needed is 3 feet, then the area of the circle will be:
