In a circle with a radius R, since the arc length of the 360° center angle is equal to the circumference length \(C=2πR\), the arc length of the n° center angle is \(l=( n°πR)/180°\) In the arc system, if the central angle of the arc is θ, then there is a for...

Welcome to the radius of a circle calculator, where we'll focus on how to find the radius of a circle from the circumference, area, or diameter. The concept is not too difficult, and, in essence, it's enough to follow a few simple steps we describe in detail below, all of which ta...
P = r ×θ, where the central angle θ = 2 × arccos [(r − h) / r] What about the area, then? You can use the segment area calculator or directly the formula for the circle segment area: A = r² × (θ − sin(θ)) / 2 Combining the two, we find the hydraulic ra...
