Show how the area of a hexagon can be used to find an estimate for the area of a circle that has a radius of 5 meters. Compare the estimate with the circle’s area found by using the formula .

Inscribe a hexagon into a circle and divide it into 6 equal triangles.

Use the measurements from Example 1 to find the area of one of the six triangles.

Find the area of the hexagon.

Compare the area of the hexagon with the area of the circle.
