WebA few important theorems are: Theorem 1: Equal chords of a circle subtend equal angles, at the centre of the circle. Converse of Theorem 1: If two angles subtended at the centre, by two chords are equal, then the chords are of equal length. Theorem 2: The perpendicular to a chord, bisects the chord if drawn from the centre of the circle. WebMay 5, 2024 · 2 Answers. Sorted by: 1. If the radius of the inscribed circle is r then the circumference is c = 2 π r while a side of the hexagon is s = 2 3 r so. s = 1 3 π c. and with c = 96 you would get s ≈ 17.643 while r ≈ 15.279. s is also the radius of the circumscribing circle. The hexagon has circumference 6 s ≈ 105.86. Share.
