Answer:
just calculate
Step-by-step explanation:
<span>The formula for the volume of a cylinder is V=πr²h. The volume of a cylinder is three times the volume of a cone with the same radius and height.
Now, volume of cone is 1/3</span>πh
<span>
If the volume of a cone with the same height as a cylinder equals the volume of a cylinder, the equation for the radius of cone in terms of the radius of cylinder R, is equal to 3R.
We get this by equating the volume of cone and cylinder:

Given that it would take 4 hours for first pipe to fill half, and 4.5 hours to fill half with other pipe u would then do 4+4.5=8.5, then 8.5/2=4.25
Answer:
s = 4
Step-by-step explanation:
3r = 10 + 5s
3×10 = 10 + 5s
5s = 30 - 10
5s = 20
s = 20 : 5
s = 4
