The Reuleaux triangle is formed from the intersection of three of these objects.
The Reuleaux triangle is formed from the intersection of three of these objects. It is given by the parametric functions x equals a cosine t and y equals a sine t, and in polar coordinates it is given by the equation r equals a. It can be formed by the intersection of a cone and a plane parallel to the base of the cone. For 10 points, give this two-dimensional geometric object with area proportional to the square of its radius.
