If a regular polygon of `n` sides has circum radius `R` and inradius `r` then each side of polygon is:

the name of a regular polygon of 3 sides is :

A regular polygon of n sides has 170 diagonals.Then n=

A regular polygon of n sides has170 digonals . Then n=

For a regular of n sides, sides are a , and circum radius is R and in-radius =r, then r+R is

The area of a regular polygon of n sides is (where r is inradius, R is circumradius, and a is side of the triangle (a) (n R^2)/2sin((2pi)/n) (b) n r^2tan(pi/n) (c) (n a^2)/4cotpi/n (d) n R^2tan(pi/n)

The area of a regular polygon of n sides is (where r is inradius, R is circumradius, and a is side of the triangle) (n R^2)/2sin((2pi)/n) (b) n r^2tan(pi/n) (n a^2)/4cotpi/n (d) n R^2tan(pi/n)
