To find volume, we will use the following equation: V=4/3piR^3
The correct answer should be 1436.76
Since 1/2x is the slope, it is proportional. The equation has a constant rise/run.

Because since there are 72 seats taken, that means there are 18 seats that are not occupied (90-72).
Then you can divide 18 by 90 to get 0.2. Multiple 0.2 by 100 to get percent.
Then you get 20%
I don’t know if that helps but here you go...
