I think this is a spreadsheet problem we're having, not a geometry one...

Problem 42: (Technology Problem) The area of a regular n-gon inscribed in a circle with radius 1 unit can be written as:

Area = (1/2)*(cos(180/n))*(2n*sin(180/n))

Use a spreadsheet to make a table. The first column is for the number of sides (n) and the second column is for Area of the n-gon. Fill in the table up to a 16-gon. What do you

Maybe the functions assume radians? 360 degrees = 2*pi radians.
