The required equation in standard form is 
Step-by-step explanation:
The equation of a circle with center (h,k) an radius, r units is given by the formula;

The given circle has center (4,5) and the radius can be calculated from the given circumference, which is 


We substitute these values into the formula to obtain;

We simplify to get;
