Question 1032156
Determine the area of a regular 18-gon with apothem 3. Use decimal approximations for your answer if needed
---------------
You can work this out using 36 right triangles.
=======
Or the formula:
{{{Area = na^2*tan(180/n)}}} n = # of sides, a = apothem
Area = 18*9*tan(10)
Area =~ 28.565 sq units
