The equation for finding the circumference of a circle:
If the radius of this circle is 1, then that means the diameter is 2. We multiply 2 by π to get our answer: 2π or approximately 6.283.
The answer: y= 6(x-7/2)^2-137/2
I think you forgot to post the figure because i do not see any sort of figure.
