Hello!
To find the volume of a cylinder, use the formula: V = πr²h.
In the formula, r is the radius, and h is height of the figure.
In the given figure, the height of the cylinder is 8 feet and the radius is 5 feet. With those values, we can find the volume of the given figure.
V = π(5)²(8)
V = π(25)(8)
V = 200π, 628.32 (multiplied by π), 628 (multiplied by 3.14)
Therefore, the volume of this cylinder is 628.32 feet cubed.
1. (5x-8)=(8x-17)
5x-8x=-17+8
-3x=-9
x=3
2. (3x+5) + (4x-7) =180
3x+5+4x-7=180
3x+4x=180-5+7
7x=182
x=26
Answer: $18
Explanation: 6x3
To get 20/10 as a mixed number you would have to take 20 and divide it by 10. Once you do that your answer should be 2.

==============================
Explanation:
The hundredth decimal place is two spots to the right of the decimal
For instance, the digit 5 is in the hundredths place for 7.3547
Since the next digit over is not 5 or larger, this means we just keep 7.35 and ignore everything else. We don't round up.
Something like 1.1295 becomes 1.12 after we drop everything after the '2', but we round up to 1.13 because of that 9 being five or larger.
The other 8 problems are handled in a similar fashion.
