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 \\ \\ (229.22)/(2) = \pi \: r \\ \\ 114.61 = \pi \: r \\ \\ (114.61)/(3.14) = r \\ \\ r = 36.5`
so the radius is 36.5
