How many circles fit

Any two circles can be made concentric by inversion by picking the inversion center as one of the limiting points. A chord that passes through the center of a circle is called a diameter and is the longest chord. If you place two radii end-to-end in a circle , you would have the same length as one diameter.

Thus, the diameter of a circle is twice as long as the radius. As you can see, a circle has many different radii and diameters , each passing through its center. And there are 16 circles. The number 6 appears here because the hexagonal lattice has 6-fold symmetry. So a natural question might be whether one can find lattices in two dimensions with, say 7-fold or 8-fold symmetry, since these might correspond to circle packings with more circles around a given circle.

The radius of a hexagon is equal to the length of one side. Because of this, a regular hexagon can be broken into six equilateral triangles. In geometry, the half circle is referred to as the semicircle. Audrone Dumann Pundit. Will a rectangle fit in a circle? Benneth, Actually - every rectangle can be inscribed in a unique circle so the key point is that the radius of the circle is R I think.

One of the properties of a rectangle is that the diagonals bisect in the 'center' of the rectangle , which will also be the center of the circumscribing circle. Waled Danke Pundit. How big of a circle can fit in a square? When a circle is inscribed in a square , the length of each side of the square is equal to the diameter of the circle. That is, the diameter of the inscribed circle is 8 units and therefore the radius is 4 units.

It can be stated that the number of inner circles depend on the diameter of the outer circle and inner circles. Inner Circular Ring Calculator. Diameter of Outer Circle length.
