we know that
circumference=2*pi*r-------> r=circumference/(2*pi)
circumference=30 in
r=circumference/(2*pi)------> 30/(2*pi)-----> 4.7746 in
the radius of a standard basketball is 4.77 in
the distance between the ball and the rim is equal to
radius of a basketball rim minus radius of a a standard basketball Â
radius of a basketball rim =18/2------> 9 in
radius of a a standard basketball=4.77 in
the distance between the ball and the rim=[9-4.77]------> 4.23 in
the answer is
4.23 in

To solve this problem you must apply the proccedure shown below:
 1. You have the following information given in the problem above:
 - The diameter of a basketball rim is 18 inches.
 - A standard basketball has a circumference of 30 inches.Â
 2. Therefore, the diameter of the standard basketball is:
 D=30 inches/π
 D=9.54 inches
 3. Therefore you have:
 (18 inches-9.54 inches)=8.45 inches on both sides
 4. Then, the distance the distance between the ball and the rim in a shot in which the ball goes exactly in the center of the rim, is:
 d=8.45 inches/2
 d=4.22 inches
 The answer is: 4.22 inches
