Answer:
9
Step-by-step explanation:
V=pi (r squared) (h/3)
75pi = 25pi (h/3)
Divide both sides by 25 pi
3= h/3
Multiply both sides by 3
h=9
3/4 would be a fraction, equivalent to 6/8.
It is the last answer letter D 8/3
I cant see the model but 2/3 is the same as 4/6
3(x-4)(2x-3)=0
(x-4)(2x-3)=0
x=4
x=3/2
