Question

I was only given the length of the diagonal. What do I do?

Community Answer

1/3rd of the length of the diagonal is the side of the hexagon. Using this, you can calculate the area.

Question

I know the area, nothing else. I need a regular hexagon. What do I do?

Question

What is the area of a regular hexagon where the length of each side is 7m?

Community Answer

The side is 1/2 of 7 = 3.5. The area of a regular hexagon is (3√3 *3.5^2)/2 =31.82 or 32 cm, approximately.

Question

What is the formula for finding the side with a given apothem and the area?

Community Answer

It's super easy to find the area of a hexagon. A hexagon is made up of 6 triangles so just find the area of each triangle, add them up, and you have your answer.

Question

How do I calculate the area of a hexagonal prism?

Community Answer

A hexagonal prism has six rectangles and two hexagons, so for a curved surface area, it will be "6 x (side of hexagon x height of prism)" and the total surface area would be "[6 x (side of hexagon x height of prism)] + 2 x (2.6 x side of hexagon)."

Question

How do I calculate the area of an irregular hexagon?

Donagan

Top Answerer

There is no applicable formula. You would have to know all of the relevant dimensions of the figure, subdivide it into sections and then add the sectional areas together.

Question

How do I find the radius of a hexagon if I know the perimeter?

Community Answer

For a regular hexagon, it's 2n (where n is the length of the side.) As for irregular hexagons, there is no other easy way than measuring it.

Question

I have an irregular hexagon, with sides measuring 1,2,3,4,5,and 6 inches. What is the formula to find its area?

Donagan

Top Answerer

There is no formula for finding the area of an irregular shape. All you can do here is subdivide the hexagon into triangles, rectangles and trapezoids, determine their dimensions and add up all their areas.
