Understanding and calculating central angles can be incredibly useful. Central angles are an integral part of geometry, astronomy, engineering, and navigation. This article will delve deep into central angles, the formula for calculating them, and introduce you to a useful tool known as the Central Angle Calculator. With this tool, you will be able to perform otherwise complex calculations with ease.
The Basics of Central Angles
A central angle is an angle that’s formed by two radii of a circle that connect the center of the circle to the points on its circumference. When calculating a central angle, the primary formula used is C = L / r where C is the central angle in radians, L is the arc length, and r is the radius. More details about this formula could be found here.
