The diameter of the smaller circle equals the radius of the larger circle.
So the diameter of the larger circle equals 4 times the radius of the smaller circle.
\(4*7=28\)

A B and C lie on the same line => centers of the two circles lies on the same line=>
the diameter of the smaller circle(B) is the radius of the bigger circle(C). Thus,
(7*2)*2=28 is the diameter of the bigger one.
