Question 1086824: A tanker truck carrying hazardous chemicals overturned on a highway, possible spilling some  of its cargo.Everyone within a 2.5 mile radius of the spill must be evacuated. The map that safety workers are using
shows the spill site at coordinates (3, 8.5). Each unit of measurement is 1 mi. Write an equation that describes the boundary of the evacuation region.

A circle of radius 2.5 centered at (3,8.5).
Start with the general equation of a circle centered at (h,k),
%28x-h%29%5E2%2B%28y-k%29%5E2=R%5E2
%28x-3%29%5E2%2B%28y-17%2F2%29%5E2=%285%2F2%29%5E2
highlight%28%28x-3%29%5E2%2B%28y-17%2F2%29%5E2=25%2F4%29
