Question

 For circle R, with point L lying on the circle, determine the circumference if RL = 34 units.

Answer 1

RL is a radius, so r = 34.

 

Circumference C = 2(pi)r; substitute into this formula; either leave PI as a factor (i.e. that letter), or use approximation 3.1416 if a decimal value is desired.
