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. 7.1 square feet 9.4 square feet 18.8 square feet 28.3 square feet

7.1  square feet

Step-by-step explanation:

Hello, great question. These types are questions are the beginning steps for learning more advanced Algebraic Equations.

In order to solve this we will need the formula that calculates the Area of a Circle. The formula is the following,

Where:

We are given the diameter of the circle in the question but based on the formula we need the radius. The radius is half of the diameter. Therefore,

Now that we have the radius we can plug it into the formula to find the area of the circle.

Based on the calculations above we can see that 7.1 (rounded to the nearest tenth) needs to painted
