Question

The circumference of a circular field is 194.68 yards. What is the radius of the field? Use 3.14 for and do not round your answer.

Answer 1

31 yards

Explanation:

194.68 / 3.14 = 62 yards

62 yards is the length of the diameter, so to get radius, divide by 2.

62 / 2 = 31 yards

Hope that helps!

Answer 2

31 yards

Explanation:

The formula to find circumference is as follows:

`c = 2(3.14)r`

We can use this to find the radius

Plug in the circumference and solve:

`194.68 = 2(3.14)r\\194.68 = 6.28r\\31 = r \\`

The radius then equals 31 yards.

Hope this helps!
