It cannot be, since no finite number of triangles can result in a smooth curve of the circumference.
Impossible
Yes.
Yes, they do.
The length of the circle's diameter
Construct a circle with a 4.5 radius. The circle's circumference is 360 degrees. So mark out 3 by 120 degrees on the circumference and join them to the centre of the circle which will divide the circle into three equal parts.
If you draw your triangles using the centre of the circle as one vertex and two more on the circumference, the area of the circle is approximately equal to the sum of the areas of the triangles; the smaller you make the triangles, the more accurate your result will be.
Impossible
To divide a circle into thirteenths, divide it into thirteen equal portions, or pieces.
Yes.
Yes, they do.
The length of the circle's diameter
It is: 12.5%
Construct a circle with a 4.5 radius. The circle's circumference is 360 degrees. So mark out 3 by 120 degrees on the circumference and join them to the centre of the circle which will divide the circle into three equal parts.
From the center of the circle, draw like a cross from there.
circle is 2d so, just fold it 15!
Not everyone knows ?
The area of the circle is equal to the combined area of the rectangles formed by cutting the circle into equal-sized triangles and placing them together side by side. This is because the circumference of the circle is equal to the perimeter of the rectangles, which means the area enclosed by the circle is equal to the area of the rectangles. This concept is known as the "circle packing theorem" in mathematics.
