Answer:
7.1 square feet
Explanation:
The area of a circle can be found using the below formula;
[tex]A=\pi\times r^2[/tex]where pi = 3.14
r = radius of the circle = d/2 = 3/2ft
Let's go ahead and substitute the above values into our formula and solve for A,
[tex]\begin{gathered} A=3.14\times(\frac{3}{2}) \\ A=3.14\times\frac{9}{4} \\ A=7.1square\text{ ft} \end{gathered}[/tex]
