Question 86235
 what is the equation of a circle with center (-1, 2) and radius 4
The standard form of a circle is: {{{highlight((x-h)^2+(y-k)^2=r^2)}}}, where the center is (h,k) and the radius is r
h=-1  k=2 and r=4
{{{(x-(-1))^2+(y-(2))^2=(4)^2}}}
{{{highlight((x+1)^2+(y-2)^2=16)}}}
Happy Calculating!!!!
