How do you find the apothem of hexagonal pyramid?

Split it into 2 30- 60- 90 triangles (split it in half) then times the short leg ( the side of the hexagon) by the square root of 3 for the apothem (4 x \/3 = apothem)


How do you find the area of a square using the radius and the apothem?

For a SQUARE, the area is (2r)2 because the length and width are the same. The apothem (radius) is used to find the area of other regular polygons.


To find the perimeter of a hexagon multiply the apothem value by six?

No, that is not correct.


What is the area of a regular octagon with a side of 6.5 and an apothem 5?

130 to find the area of any regular polygon, multiply the perimeter by one-half the apothem. This is the same as multiplying the side-lengths by the number of sides by one-half the apothem.

Find the area of a regular 7-gon with a side length of 12?

You can find the area of any regular polygon with this equation: 1/2ap where a is the apothem and p is the perimeter.To find the perimeter, multiply 7 times 12 to get 84.To find the apothem, divide 360 (the amount of degrees around the center of the polygon) by 7 (the amount of sides you have) to get about 51.43. This gives you the measure of the angle of one triangle connected to 2 adjacent vertices. You have to make this a right triangle so that you can use trigonometry to find the apothem, so divide that angle by 2 to get 25.72. You know the side opposite of this angle is 6 because it is half the amount of the side (remember we divided this triangle by 2). To find the apothem at this point, use trigonometry. tan25.72 = 6/x. The apothem is 12.46.So, plug all of this into your calculator; a = 1/2(84)(12.46). You find the area to be about 523.3.
