Answer:
1. 14476.46
2. 25333.8
3. 19142.66
Step-by-step explanation:
Ok lets take this slow...
First, read the directions; they want you to find how much water the barrles will hold, also meaning how much space is inside the barrel? This can be a hint to find for the area of the barrles.
The formula for a cyliner is: A=2πrh+2πr^2
You already have the information to solve the formula so all you have to do is plug the amounts in, whitch would look like this.
A= 2(3.14) (72) + 2(3.14) (24) ^2
72 * 3.14 24 * 3.14
A= 2 (226.08) + 2(75.36)^2
452.16 + 2 (5679.1296)
452.16 + 11358.2592
A≈ 14476.46
You would do the same for barel B and get: 25333.8
now subtract Barral A by Barral B to find the diffrence
144476.46 - 25333.8
The diffrent of barrle A and B is 19142.66
