Question

The circumference of a circular field is 229.22 yards. What is the radius of the field? Use 3.14 for π and do not round your answer.

Answer 1

$c = 2\pi \: r \\ \\ 229.22 = 2\pi \: r \\ \\ \frac{229.22}{2} = \pi \: r \\ \\ 114.61 = \pi \: r \\ \\ \frac{114.61}{3.14} = r \\ \\ r = 36.5$
so the radius is 36.5
