WebFeb 11, 2024 · Using this, we can start with the maths: A₀ = a × h / 2. = a × √3/2 × a / 2. = √3/4 × a². Where A₀ means the area of each of the equilateral triangles in which we have divided the hexagon. After multiplying this area by six (because we have 6 triangles), we get the hexagon area formula: A = 6 × A₀ = 6 × √3/4 × a². WebThe Math. The formula for the length of a chord is: d = 2•r•sin (a/2r) where: d is the length of the chord. r is the radius of the circle. a is the arc length. The length of the chord (d) is the distance between two points on a circle. θ= a / r. WebGeometry Calculators.
