A circle with radius 12 has its center at one vertex of a square. If the square has side length 12, find the area of the red region.
If each unit circle passes through the centers of the other 2 circles, what is the perimeter?
Do not include the parts that are contained within the figure.
I have a square with side length 10.
I cut out 4 rectangles from each of its corners as shown above.
What is the perimeter of this new figure?
In the diagram above, a yellow regular hexagon lies inside a larger regular hexagon with twice as large a side length.
Each of the 3 line segments connecting the inner and outer hexagons has the same length as a side of the yellow hexagon.
Is it true that the 4 colored regions have the same area?
