Question 39167
If all the sides are all the same length:
you would divide 360 degrees by 7 to get that each "triangle" has a degree of about 51.4 degrees ....
Use tan(51.4/2) = (25/x) because the right triangle is bisecting
{{{x}}} is about 51.9130349
that is apothem .... multiply it by 350 to get the area of about 18,170
