Bill measures the circumference of a circular fish pond to be 28 ft.

What is the diameter of the fish pond, rounded to the nearest foot?
Use 3.14 to approximate pi.

Circumfrence of a circle formula:


C=\pi d
(C = circumfrence, π = pi, d = diameter)

Let's plug in what we know.


28=3.14d

Divide each side by 3.14 to find d.


8.917\approx d

Round to the nearest foot...


\boxed{d\approx9}
