So we're given the dimensions of circle C and then we're told circle F has the radius R.
1 tells us that the distance between the two circles is 1+R. If the two circles were separated by more than their radii combined, it means that they don't intersect. However, 1+R is less than the radius of circle C and the radius of Circle F combined (2+R). Therefore, circle C and circle F intersect at 2 points (if 1+R=radius of circle C and circle F, it would be tangent).

2 tells us the value
