In mathematics, a unit circle is a circle of unit radius—that is, a radius of 1. Frequently, especially in trigonometry, the unit circle is the circle of radius 1 centered at the origin (0, 0) in the Cartesian coordinate system in the Euclidean plane.
If there are 3 feet per yard, then all you have to do is take the 96 feet and divide by 3, this gives you 32 yards.
