Question

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

Answer 1

18.8

Explanation:

Answer 2

7.1 square feet

Explanation:

Since the diameter of a circle is twice the radius, the radius of each circle is 3/2=1.5. The area of a circle is
`\pi r^2=\pi \cdot 1.5^2=2.25\pi \approx 7.1`. Hope this helps!
