Answer:
Center (4,1)
Radius r = 4
Step-by-step explanation:
Complete the square to fill in the standard circle equation:
- [tex](x-h)^2+(y-k)^2=r^2[/tex] , (h,k) is the center, r is the radius
[tex](x^2-8x+16) + (y^2-2y+1) = 16[/tex]
Use formula: [tex]x^2+2ax+a^2=(x+a)^2[/tex]
therefore, [tex](x-4)^2+(y-1)^2=16[/tex]
(h,k) = (4,1)
r = 4
