For circle E, with point l lying on the circle, determine the circumference if RL=34 units

Question

This is Geometry, circumference of a circle 

Answer 1

We need more info. Where is point R located? The center?

 

If so, you can easily solve it by using 2*pi*r = Circumference, where r is the radius. If R is the center, then RL should be the radius.
