what is the equation of a circle with center (-1, 2) and radius 4
The standard form of a circle is: highlight%28%28x-h%29%5E2%2B%28y-k%29%5E2=r%5E2%29, where the center is (h,k) and the radius is r
h=-1 k=2 and r=4
%28x-%28-1%29%29%5E2%2B%28y-%282%29%29%5E2=%284%29%5E2
highlight%28%28x%2B1%29%5E2%2B%28y-2%29%5E2=16%29
Happy Calculating!!!!
