56 pages/4 hours = 126 pages/x pages
Then you cross multiply
56*x =4*126 ---> 56x=504
Then you divide 56 to both sides
56x/56=504/56
The 56 cancels on the left side and then you get
x=9
So your proportion are:
56 pages/4hours=126 pages/9 hours
Let's simplify the equation:
V=πrh^2 - (πh^3)/3
πrh^2=V + (πh^3)/3
πrh^2=(3V + πh^3)/3
r = (3V + πh^3)/3πh^2
Answer:
Kathryn thinks that the 3 is the age and the 10 is how many are that age. 10 is thr age and the 3 "x's" are how many people are 10 years old.
Hope this helped!
Answer:
h = 6
Step-by-step explanation:
πr²h = 384π
Divide by pi on both sides.
r²h = 384
8²h = 384
64h = 384
Divide by 64 on both sides to isolate h.
h = 6
