The equation of a circle is (x−2)^2+(y+6)^2=100. Find an equation to the circle that is internally tangent to the given circle and has center at (2, -10). I got an answer of (x-2)^2+(y+10)^2=36, and I entered it in an I got an incorrect answer. I think that I need multiple answers, because it says "Leave unused fields blank," even though I can't find any other possible answer. I don't know if it's a typo in the system or not.
