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.
diameter of a circle = 2*radius or circumference/pi
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
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
SA equals pi times the radius squared
how to calculate the elbow radius or elbow length
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
You can use the cosine rule to calculate the central angle.
Circumference = 2*pi*radius
The length of a tube is not related to its radius so you cannot.
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).

When you have this, simple multiply both sides by the radius to isolate the a. Once you do this, you have your answer.
To calculate volume of water for hydro test you need to use the formula pi times radius (squared) times length. Pi is equal to 3.14.
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
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
Area of rod = length*diameter*pi
Calculate the area of the circle of 101 mm radius. Multiply this by the length of 656 mm. Divide the result by 1,000.
You don't. You can calculate iits radius and cross-sectional area but its diameter has insufficient information to calculate its length
