C=2pi%2Ar Start with the circumference of a circle formula.


C%2F%282pi%29=r Divide both sides by 2pi to isolate "r".


r=C%2F%282pi%29 Flip the equation.


r=10%2F%282pi%29 Plug in C=10 (the given distance of the rope).


r=10%2F%282%2A3.14159265%29 Replace pi with 3.14159265 (note: Use more digits of pi to get better accuracy).


r=10%2F%286.2831853%29 Multiply 2 and 3.14159265 to get 6.2831853.


r=1.59154943273756 Divide 10 into 6.2831853 to get 1.59154943273756 (this figure is approximate).


So the radius of a circle which has a circumference of 10 meters is about 1.59154943273756 meters.
