What is a Unit Circle in Math?A unit circle is a circle of unit radius with center at origin. A circle is a closed geometric figure such that all the points on its boundary are at equal distance from its center. For a unit circle, this distance is 1 unit, or the radius is 1 ...
A circle is a locus of all the points equidistant from a fixed point to the outer boundary. Learn its definition, construction of the circle, formulas for area and circumference with solved examples.
