Heptagon calculations

An heptagon is a polygon with seven sides. With this tool you can compute area, radius R of circumscribed circle, side t, apothem r, circumference, d diagonal, height h of regular convex hexagon. You just enter a value so that the other ones are computed. α angle between the sides of a regular heptagon is 128.57° and the ratio between diagonal d and side t is equal to 2.24698. area in m2 radius R in metre m side t in metre m apothem r in metre m diagonal d in metre m circumference 7t in metre m height h (r+R) in metre m Note Copyright © 1997-2025 FXTOP
