The correct answer (somewhat) is how Project Manager did it without pi. The reason why...because the question didn't ask you to solve it with a standard formula..ie..area of a circle. It said use the following chart. Also, this is an algebraic problem, not a geometry problem.

This is similar to introductory algebra problems that give a chart of x,y coordinates and asks the student to graph a line or function from them. Basically connect the dot. It's much different if you only give the student two sets of coordinates and ask them to figure out the slope(,) y1-y2/x1-x2 and then take that and then figure out y=mx+b to graph it. If you want to know what kind of answer you have to give, you need to understand exactly what question you are being asked...and what constraints you are under. In this case....simply using the chart. Otherwise you would have been given all the area formulas for the problem..

Project Mangers way...is correct, but probably not what they are looking for..

22^2 / 18^2

The reason you don't need to use PI in the formula is because it's a constant between the both sizes.

The more true method to using the chart is to take the given data and solve for X where X equals the rate of area expansion per 2 inches...or whatever other relational data you can obtain from the chart between the sizes...ergo...per example..filling out the next value for 18" would be a 1.00 value because of the 1:1 equal ratio

18" pizza = 0.65 22" pizza
18" pizza = X.XX 20" pizza
18" pizza = 1.00 18" pizza
18" pizza = 1.25 16" pizza
18" pizza = 1.65 14" pizza
18" pizza = 2.25 12" pizza
18" pizza = 3.25 10" pizza
18" pizza = 5.00 8" pizza

I dont' need the five dollars. I'd like to see who here on the board can actually solve it the right way. The person who figures it out just using the chart and posts the method will be the true person that earns the 5 bucks...

Also...its pretty clear they are rounding numbers to the nearest tenth or half tenth. Which would be 1.5. If you want to get technical and really answer the question by fitting shit into the chart...the number they are looking for is actually the other way..which would be .65 (hint on how to solve it if you look at the chart)
