I think you can chose your own points like (0,296) and (2,592)
volume - pi*r^2*H
Lets use 3.14 for pi
R = radius which is half the diameter so half of 3 is 1.5
H = 6
so volume = 3.14*1.5^2*6 = 42.39in^3
The true answer is
<span>n = 0.32(75)
the
</span>32% of 75 is calculated with 23 x 75 / 100 = <span>0.32(75)</span>
