The diameter of a basketball rim is 18 inches. a standard basketball has a circumference of 30 inches. what is the distance between the ball in the room in a shot in which the ball goes exactly in the center of the room? show your work
so much in advance ! : ))

The distance between the ball in the room is

Step-by-step explanation:

We know that for a circumference the radius is equal to half the diameter.

The diameter of the basketball hoop is 18 inches.

Then the radius of the hoop is:

If, the circumference of the ball is 30 inches then the circumference C is:

And the radius of the ball is:

So the distance between the ball and the ring will be equal to the difference of both radius.

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
