The volume of any cylinder is
Volume = (pi) x (radius of a round end)² x (height)
= (pi) x (6.1-ft)² x (1.8-ft)
= (pi) x (37.21 square feet) x (1.8-ft)
= <em>66.978 π cubic feet
</em>Since π (pi) can't be written exactly, no number it appears in
can be written exactly either. The only way to indicate the
exact value of such a number is to leave the symbol 'π' in it.

Step-by-step explanation:
Add everything up then subtract $842000 by it
Answer:
y = 60
Step-by-step explanation:
From the information we get:
x quantity of 4 dollars coffee used in the mix
y quantity of 7 dollars coffee used in the mix
For the quantity of coffee to be sold a 7 $/pound ( 90 pounds)
Then 6*90 = 540 $
Therefore
x + y = 90 and
4*x + 7*y = 540
A two equations system we solve for x and y
y = 90 - x
4*x + 7* ( 90 - x ) = 540
4*x + 630 - 7*x = 540
- 3*x = - 90
x = 30 pounds and
y = 90 - 30
y = 60
We should use 60 pounds of the seven $ coffee
Yes, you always can divide by e^x because e^x ≠ 0 for x∈R.
