Question 1153881
<br>
{{{(x-h)^2+(y-k)^2 = r^2}}}  <---> center (h,k), radius r<br>
Example: center (3,-2) and radius 5  -->  {{{(x-3)^2+(y+2)^2 = 25}}}<br>
Example: {{{(x+1)^2+(y-4)^2 = 16}}}  -->  center (-1,4), radius 4<br>
You are given the center (h,k); and with the given other point, the radius r is easy to find....
Simply plug those values in the formula.<br>
