because the 8 makes the 9 round up into a 10
2a+1b=27.50
4a+2b=59.50
Multiply first equation by -4 and the second by 2 so you can drop off the a values then add the equations together. Then solve for b. You should get b=6.
Then plug b into one of the original equations and solve for a and you should get 10.75
So a plate of spaghetti is $10.75 and a salad is $6.

Answer
Find out the volume of a cylinder .
To prove
Formula
Where r is the radius and h is the height.
As given
Diameter of 12 in. and a height of 7 in.
Radius = 6 in
put all the values in the formula
= 791.28 in³
Therefore the volume of the cylinder is 791 .28 in³ .
There is no correlation it’s a scattered plot
