CCSS IP Math II 6.5.1 Example 2

Area, Circle
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 .
  1. Inscribe a hexagon into a circle and divide it into 6 equal triangles.
  2. Use the measurements from Example 1 to find the area of one of the six triangles.
  3. Find the area of the hexagon.
  4. Compare the area of the hexagon with the area of the circle.
