Answer 3

"What is the distance between the ball and the rim in a shot in which the ball goes exactly in the center of the rim?"

so they want this distance

Answer 4

Is there an equation I can use?

Answer 5

Answer 6

"A standard basketball has a circumference of 30 inches"

what is the diameter of the ball?

Answer 7

I'll be right back

Answer 8

The diameter of the ball is 15

Answer 9

Whats next?

Answer 10

@jim_thompson5910

Answer 11

circumference = \[2\pi r\]

Answer 12

C = 2*pi*r like DarkBerrt points out

30 = 2*pi*r

r = ???

Answer 13

or
this might be easier for this question: c= pi*D

Answer 14

So

C = 2 * pi * r

30 = 2 * pi * r

How do I find r?

Answer 15

use a calculator

Answer 16

No duh. What do I do to find r?

Answer 17

divide both sides by 2pi to isolate r

Answer 18

So 30 / 3.14?

Answer 19

c=2*pi*r
30=2*pi*r
15=pi*r
now use calculator since question doesn't ask in terms of pi

Answer 20

30 = 2 * pi * r

*Divide pi by both sides*

9.55414013 rounds to 9.6

9.6 = 2

*Subtract 2 on both sides*

9.6 - 2 = 7.6

Answer 21

Like that? @jim_thompson5910 @DarkBerrt

Answer 22

step one is perfect; now step 2..... where did the r go??
