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. examples of giving feedback

"WebThe general equation of a circle is (x - a) 2 + (y - b) 2 = r 2, which represents a circle having the center (a, b) and the radius r. This equation of a circle is simplified to represent the equation of a unit circle. A unit circle is formed with its center at the point (0, 0), which is the origin of the coordinate axes. and a radius of 1 unit. " - Trinangle inside the unit circle
