Chord area formula
WebFeb 9, 2024 · a stands for the area of the circle. It is the only value expressed in squared units (for example, cm²). You can calculate it as follows: If you know the radius or diameter of the circle, the area of the circle formula is: a = πr² = π × (d / 2)². If radius and diameter are unknown, you can calculate it from the circumference: a = c² / 4π WebMar 24, 2024 · A portion of a disk whose upper boundary is a (circular) arc and whose lower boundary is a chord making a central angle theta

A sector always emerges from the centre of the circle. The semi-circle is also a sector of a circle. An arc and a circle chord bound the area of sector and segment of a circle. When we divide something into parts, each part is referred to as a segment.
Let R be the radius of the arc which forms part of the perimeter of the segment, θ the central angle subtending the arc in radians, c the chord length, s the arc length, h the sagitta (height) of the segment, d the apothem of the segment, and a the area of the segment. Usually, chord length and height are given or measured, and sometimes the arc length as part of the perimeter, and the unknowns are area and sometimes arc length.
