To calculate the position of the 12 squares aligned around the edges of a perfect dodecagon, you can use the following steps:
Calculate the radius of the dodecagon:
The edges of the dodecagon are 576 units long, and the dodecagon is a regular polygon, so the radius can be calculated as:
Radius = (Edge Length) / (2 × tan(π/12)) = 576 / (2 × tan(π/12)) ≈ 500.00 units
Calculate the position of the centers of the squares:
The squares are 576 × 576 units, so their centers will be 288 units away from the edge of the dodecagon.
The centers of the squares will be evenly spaced around the dodecagon, with an angular separation of 30 degrees (360 degrees / 12 squares).
The coordinates of the centers of the squares can be calculated using the following formulas:
x = (Radius + 288) × cos(θ)
y = (Radius + 288) × sin(θ)
Where θ is the angle of the square, starting from the positive x-axis and increasing counterclockwise.
Applying these formulas, the coordinates of the centers of the 12 squares are:
(681.40, 1801.21)
(1365.45, 1117.77)
(1365.45, -1117.77)
(681.40, -1801.21)
(-681.40, -1801.21)
(-1365.45, -1117.77)
(-1365.45, 1117.77)
(-681.40, 1801.21)
(0.00, 2000.00)
(1000.00, 1732.05)
(1000.00, -1732.05)
(0.00, -2000.00)
Okay, let's solve this step-by-step:
We have a regular dodecagon with edge length of 576 units.
The dodecagon is centered at (0, 0).
You want to place 12 squares of size 576 x 576 units around the edges of the dodecagon.
The squares should be rotated 30 degrees more than the previous one.
To calculate the position of the centers of the 12 squares:
The angle between each square is 360/12 = 30 degrees.
The radius of the dodecagon is 576 / (2 * tan(π/12)) = 500 units.
The center of the first square is at:
x = 500 * cos(0) = 500
y = 500 * sin(0) = 0
The center of the second square is at:
x = 500 * cos(30 * π/180) = 433.01
y = 500 * sin(30 * π/180) = 250.00
Continuing this pattern, the coordinates of the 12 square centers are:
| Square | X | Y |
| --- | --- | --- |
| 1 | 500.00 | 0.00 |
| 2 | 433.01 | 250.00 |
| 3 | 250.00 | 433.01 |
| 4 | 0.00 | 500.00 |
| 5 | -250.00 | 433.01 |
| 6 | -433.01 | 250.00 |
| 7 | -500.00 | 0.00 |
| 8 | -433.01 | -250.00 |
| 9 | -250.00 | -433.01 |
| 10 | 0.00 | -500.00 |
| 11 | 250.00 | -433.01 |
| 12 | 433.01 | -355.o1
The coordinates are rounded to two decimal places, as requested.
All answers are positive, negative and reverse (X,Y) of the following 2 sets

Yes, they tessellate with squares and hexagons. For every dodecagon , there are 6 squares and 6 hexagons to go around it. They tessellate because every = exterior angle on a dodecagon = 150 degrees . every interior for a hexagon - 120 degrees . every interior for a square - 90 degrees. This adds up to 360 at a point and this is why they tessellate perfectly

4, 6, 8 or 12, depending on how many sides are aligned with one another.
Count the number of squares across the top of the grid, the count the number of squares down the side of the grid. Then multiply these two numbers If you have a grid of 100 squares by 60 squares then the number of squares in the grid is 100x60 = 6000
There is no single formula.It is necessary to calculate the total sum of squares and the regression sum of squares. These are used to calculate the residual sum of squares. The next step is to use the appropriate degrees of freedom to calculate the mean regression sum of squares and the mean residual sum of squares.The ratio of these two is distributed as Fisher's F statistics with the degrees of freedom which were used to obtain the average sums of squares. The ratio is compared with published values of the F-statistic since there is no simple analytical form for the integral.
The middle squares never move so the answer is 6.
You could count them, or you could look at it, notice that there are 3 rows of 4 squares, and recall that (3 x 4 = 12).
You do not. As two-dimensional shapes geometric squares have area and no volume whatsoever.
The length of the hypotenuse is equal to the root of the sum of the squares of the other two sides.
If you're talking about a perfect circle and perfect squares, I would say probably about 3.1415926 squares would fit into a circle. So, about 3: but a little more. - Josh
a roofing square is 100 sf. There are formulas out there that allow you to use the pitch and outer dimensions of the roof to figure out the number of squares. If not, calculate the square footage and divide by 100 - that's the number of squares you have...
