The center of a circle is (4, -2). (4, 7) is outside the circle, and (1, -2) is inside the circle. If the radius, r, is an
integer, how many possible values are there for r?
Choose the correct choice from the following
A) 4
B) 2
C) 1
D) 10
E) 11
r must be greater than 3 and smaller than 9, hence r=4,5,6,7 or 8.   4nswer 4
