Answer:
See below in bold.
Step-by-step explanation:
(A) 20 -4x=12 -x+8-3x
-4x + x + 3x = 12 + 8 - 20
0 = 0 This is an Identity.
Infinite solutions.
B). 5x+4x-3=24+8x
9x - 8x = 24 + 3
x = 27. One solution.
C. 5x+6=2x+6+3x-15
5x - 2x - 3x = -15 + 6 - 6
0 = -15
No solution.
Answer:
The 3rd

Well, let's do the math. The formula of a cylinder is 2 (pi, which will be estimated to 3.14) r h + 2 pi (radius times radius).
First of all, do 2 x pi, which is 6.28. Multiply 6.28 x 1.4 is 8.792. 8.792 x 5 = 43.96.
Now for 2 times 3.14 again, which is 6.28. But this time, we do 1.4 x 1.4, which is 1.96. With our new number, we do 6.28 x 1.96, which is 12.3088.
Add 43.96 + 12.3088, and you get 56.2988. You can round it to 56.3. So, the answer is 56.3 inches.
