Question

If the side of a regular hexagon is 10 cm then the radius of its circumcircle is​?

Answer 1

10 cms.

Explanation:

The circumcircle passes through each vertex of the hexagon so the radius is equal to one of the 2 equal sides of an isosceles triangle with base = 10 cm and vertex = 60 degrees.

So considering this triangle the base angles are ( 180 - 60) / 2 = 60 degrees. So we have an equilateral triangle with each side = 10 cm.

Therefore the radius is 10 cm. long.
