Question 417507
Write an equation in standard form for each circle.
If the center is (h,k) and the radius is "r", the 
equation is (x-h)^2+(y-k)^2 = r^2
------------------------------------- 
5. (0,0), radius 3
x^2 + y^2 = 9
-----
6. (0,2), radius 8
x^2 + (y-2)^2 = 8^2
--------------------- 
7. (5, –1), radius 6
(x-5)^2 + (y+1)^2 = 36
