Find the sum of the interior angles for a hexagon.

a) 540°

b) 720°

c) 900°

d) 1,080°

To find the sum of the interior angles of a hexagon, we can use the formula:

Sum of interior angles = (n-2) * 180°, where n is the number of sides of the polygon.

In this case, since we have a hexagon (a polygon with 6 sides), we can substitute n = 6 into the formula:

Sum of interior angles = (6-2) * 180° = 4 * 180° = 720°

Therefore, the correct answer is b) 720°.
