Question

If the length of each side of regular hexagon is 9cm what is radius of circle in cm

Answer 1

Answer:

It's inscribed in a circle. If its every vertex is joined with the centre of the circle, you will find that central angle,that is 360° is divided into 6 equal parts. So each angle at the centre = 60°. Now radius = 12cm.

Answer 2

Given:

The length of each side of regular hexagon is 9 cm.

To find:

The radius of circle in cm.

Step-by-step explanation:

Area of a regular hexagon,

$=\frac{3\sqrt{3} }{2} (side)^2$

$=\frac{3\sqrt{3} *9^2}{2}$

$=210.4.sq.cm$

Answer:

The radius of circle in 210.4 sq.cm
