You can put this solution on YOUR website! Here is the equation of a circle: (x-1)^2 + (y+6)^2=15. How do you find the circumference of the circle? How do you write the circumference in terms of pi?
------------------------
All you need is the radius of the circle.
---
radius = sqrt(15)
----
Circumference = 2(pi)r = 2*sqrt(15)(pi) ~ 24.335 units
