The equation of a circle is (X+12)^2+(y+16)^2=r^2, and the circle passes through the origin. The equation of the circle then changes to ( x-30)^2+(y-16)^2=(r2)^2 and the circle still passes through the origin. What are the values of r1 and r2? Answers: r1 = 10 and r2 = 17 r1 = 10 and r2 = 34 r1 = 20 and r2 = 17 r1 = 20 and r2 = 34

The ratio would be 3:7
240 divided by 3 is 80
You need to multiply 7 by 80
7x80=560
560+240=800
