I want to make circles of various sizes out of nylon rope to use as
targets for practicing short golf shots. The method I am using calls
for the target circle to have a radius that is 1/10 of the length of
the shot. If I am practicing 10-yard chip shots, I would need a target
circle with a radius of 1 yard. For 30-yard pitch shots, I'd need a
target circle with a radius of 3 yards.

Why not put a small loop in one end and thread the other end through it.
Then if you mark the rope you just pull through to you get the distance you
want.
