How to Calculate the Radius Given the Diameter The diameter of a circle is equal to twice the length of the radius. So, you can use the following formula to calculate the radius when given the diameter: r = d/2 Thus, the radius of a circleris equal to the diameterddivided by 2. ...
This is the diameter of a circle that corresponds to the specified radius. The diameter of a circle is the length of a straight line drawn between two points on a circle where the line also passes through the centre of a circle, or any two points on the circle as long as they are ex...
Circumference of Circle This is the total length of the edge around the circle with the specified radius, if it was straightened out. Primary Sidebar Tool Feedback Please provide feedback on using thisRadius to Circumference of Circle Calculator....
Radius Calculator allows you to calculate the radius, central angle, arc length, and circumference from the span / chord and rise of an arc segment. Built-in unit converter makes it to work with any length unit (including inches, feet, centimeters, meters, and many more). Simply enter the...
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...
The length arcsis equal to the radiusrtimes the central angleθin radians. Unit Circle Theunit circleis a circle with a radius equal to 1, centered on the origin (0, 0). It is used to calculate the cosine, sine, and tangent of any angle within the circle, although it is most commo...
