WebA unit circle is typically drawn around the origin (0,0) of a X,Y axes with a radius of 1. For a straight line drawn from the circle’s centre point to a point along the circle’s edge, the length of that line is always 1. This also means that the circle’s diameter is equal to 2 because the diameter is equal to twice the length of the radius. WebA point with coordinates ( a, b) is in the unit circle if and only if a 2 + b 2 = 1. Explanation: The unit circle is by definition a circle with radius equal to 1 and center ( 0, 0), so the …
