Answer:
Cost to rent one tank=226.08 Dollars
Step-by-step explanation:
Radius of the cylindrical tank=3 feet
Height of the tank= 2 feet
Cost to rent one tank= Volume of one tank * cost to rent one cubic feet of volume
Volume of the cylindrical tank:
=
As, 
Putting the values in the formula:
Volume of the tank:

Cost to rent one cubic feet= 4 Dollars
Cost to rent 56.52 Cubic feet of one tank;
= 4*56.52
=226.08 Dollars
The number of hours he worked in all (written in fraction form) is 
From the question,
Mario worked from 8:25 to 12:45 yesterday.
From 8:25 to 12:45 gives 4 hours 20 minutes
Also, from the question,
Today he will work from 11:20 to 3:10
From 11:20 to 3:10 gives 3 hours 50 minutes
To determine the number of hours he work in all, we will add the time spent working on the previous day to that of the current day. That is,
4 hours 20 minutes + 3 hours 50 minutes = 8 hours 10 minutes
Now, to put the answer in fraction form, we will convert 10 minutes to hours
NOTE: 60 minutes = 1 hour
∴ 10 minutes =
= 
∴ 8 hours 10 minutes = 
Hence, the number of hours he worked in all (written in fraction form) is

Use the difference of squares factorization - that for any numbers a and b, (a-b)(a+b)=a^2-b^2.
We have:
(x^2+1)(x^2-1)=x^4-1
In addition:
(x-1)(x+1)=x^2-1, so we have:
(x^2+1)(x+1)(x-1)
As our complete factorization.
