the length is: 2rsin(1/2 theta) where r is the radius and theta is the included angle.
To find the arc length given the radius and angle measure in degrees, you must first convert the angle from degrees to radians, using the formula: Degrees = Radians X (pi/180). Then take the radians and the radius that you are given, and put them into the formula of Q = (a/r) where Q is the angle in radians, a is the arc length, and r is the radius. When you have this, simple multiply both sides by the radius to isolate the a. Once you do this, you have your answer.
Well, isn't that just a happy little question! To find the radius when you have the angle and arc length, you can use the formula: radius = (arc length) / (angle in degrees) * (π/180). Just plug in the values you have, and you'll have your radius in no time. Remember, there are no mistakes, just happy little accidents in math!
R = radius c = chord length s = curve length c = 2Rsin(s/2R) you can solve for radius by trial and error as this is a transcendental equation
diameter of a circle = 2*radius or circumference/pi
The formula to calculate radius is Pi x Diameter. So, if the radius is 7, the diameter is 14. Then, do 14 x pi (3.14) and your circumference will be 43.96
how to calculate the elbow radius or elbow length
To calculate the edge length of a face-centered cubic structure, you can use the formula: edge length (8/3) radius.
To find the arc length using radians, you can use the formula: Arc Length Radius x Angle in Radians. Simply multiply the radius of the circle by the angle in radians to calculate the arc length.
You can use the cosine rule to calculate the central angle.
To calculate the volume of a pipe, you can use the formula for the volume of a cylinder: Volume = πr^2h where r is the radius of the pipe and h is the height (length) of the pipe. Measure the radius and length of the pipe, plug them into the formula, and solve for the volume in cubic units.
You need to know the radius (1/2 the inside diameter) and the length of the pipe. Then, you use this formula to calculate the volume:Pi (3.1416) x r2 x length
The formula used to calculate the capacitance of a cylindrical capacitor is C 2L / ln(b/a), where C is the capacitance, is the permittivity of free space, L is the length of the cylinder, b is the outer radius, and a is the inner radius.
The length of a tube is not related to its radius so you cannot.
Circumference = 2*pi*radius
To find the arc length given the radius and angle measure in degrees, you must first convert the angle from degrees to radians, using the formula: Degrees = Radians X (pi/180).

the formula for the arc of a triangle is the arc length is equal to the angle times the radius. s=arc length theta=angle made y length of the arc lenth r=radius s=theta times radius
For a rectangle: length times width For a triangle: length times width divided by two For a circle: pie times radius squared For a rectangular prisim: length times width times height For a sphere: four thirds pie times radius cubed
