Hi Muhammed -

For the formula C = 2Πr

C is the circumference

Π is the constant pi = 3.14

r is the radius

To find the radius, you would just need to divide both sides of the equation above by Πr

That gives:

r = C / 2Π

From the problem description, the circumference C = 73 yds

As noted above, Π = 3.14

Just plug these values in the equation above to give you the radius in yds.

Hope this helps.

Muhammad J.
