You know you are finished dividing when you can no longer simply & when you plug it back in to check the answer
Step-by-step explanation:
formula to find volume of a cylinder => V= πr²h
(22/7×(3.5)²×12)cm³
462cm³.
now the total volume of plastic used is = 462×0.2 = 92.4cm³.
hope this helps you.

Answer:
x= 8 y= 1
Step-by-step explanation:
First, you identify your variables:
x= larger number
y= smaller number
Second, you find your equations:
x - y = 7
2x + 3y = 19
Third, (I used the substitution method) you make "y" by itself for the 1st equation.
y = x - 7
2x + 3y = 19
Then, you plug in the 1st equation for "y" in the 2nd equation
2x + 3(x - 7) = 19
Then, you distribute and simplify.
2x + 3x - 21 = 19
5x - 21 = 19
5x = 40
x = 8
Finally, you plug in the variable you found ( x ) into one of the equations and solve,
8 - y = 7
- y = -1
y = 1
