The area of the circle is given by:

[tex]\pi\cdot r^2[/tex]

where r is the radius of the circle

Given area = 615.8 yd^2

so, we will calculate the radius of the circle as follows:

[tex]\begin{gathered} \pi\cdot r^2=615.8 \\ r^2=\frac{615.8}{\pi}=196.015 \\ \\ r=\sqrt[]{196.015}\approx14yd \end{gathered}[/tex]

So, the radius of the circle = r = 14 yd

The circumference of the circle =

[tex]2\cdot\pi\cdot r=2\cdot\pi\cdot14=87.9646[/tex]

rounding the answer to the nearest tenth

So, the circumference = 88 yd
