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. ...
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...
How to Calculate the Radius of a Sphere?The distance from the center to any point on the circumference of a sphere is known as the radius. We know that the size of a sphere changes when the length of the radius varies. Now, let us see how to find the radius of a sphere when the...
If your pipe is only half full, the wetted perimeter will be equal to half of the total perimeter: P = πr What happens if the pipe is not exactly full or half full? In that case, the wetted perimeter is equal to the arc length, corresponding to the central angle θ, as shown in...

This geometry calculator will take one known circle measurement (area, circumference, diameter, or radius) and calculate the other three. Plus, unlike other online circle calculators, this calculator will show its work and give a detailed, step-by-step explanation of the formulas and sequence ...
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...
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...
