Answer:

Step-by-step explanation:
The volume of a cylinder is:

where
is the radius and
is the height.
The height is 4 inches greater that the radius, so:

Substituting this in the formula for volume:

the volume is 
thus:

Dividing everything between pi:


We can see that the solution for this is 
since 
We have the radius, now we find the height:


Answer:
1596.2 ft/m
Step-by-step explanation:
<u>Data</u>
- height of water, h = 11 ft
- acceleration of gravity, g = 32.17 ft/s²
Given that 60 seconds are equivalent to 1 minute:
g = 32.17 ft/s² * 60² s²/1 min² = 115812 ft/min²
From Bernoulli's theorem:
velocity = √(2gh)
velocity = √(2*115812*11)
velocity = 1596.2 ft/m
He should make 20 dining chairs, and 10 rocking chairs. Making a profit of 2100$
10 rocking chairs x 2hrs = 20hrs
20 dining chairs x 1 = 20hrs
20hrs + 10hrs = 30hrs
90 x 10 = 900$
20 x 60 = 1200$
900 + 1200 = 2100$
