Where,

a = length of each side of the polygon

n = no. of sides of the regular polygon

c = central angle

i = interior angle

I = sum of interior angles

R_i = in-radius of the regular polygon

R_c = circumradius of the regular polygon

P = perimeter of the regular polygon

A = area of the regular polygon
