What is the formula for calculating the central angle given chord length and radius?
You can use the cosine rule to calculate the central angle.
How do you calculate the length of an arc of a circle?
The length of the arc is equal to the radius times the angle (angle in radians). If the angle is in any other measure, convert to radians first. (radians = degrees * pi / 180)
What type of angle is formed by a tangent and a radius?
The angle between the radius and the tangent is a right angle of 90 degrees.
How do you calculate circle diameter?
The answer depends on what information about the circle is given: area, radius, length and angle of arc, area and angle of sector, etc. In each case, there is a different way to calculate the diameter but, since there is no information on what is known, it is not possible to answer the question.
How do you calculate radius of the circle when you do not have diameter?
Double the Radius to Calculate the Diameter.
What is the formula to calculate the length of a chord given the included angle and radius?
the length is: 2rsin(1/2 theta) where r is the radius and theta is the included angle.
How do you calculate angle with only number of sides and radius?
There is not enough information to calculate an angle. At the very least, you need to know that the polygon is regular. You do not know that.
What is the formula for calculating the central angle given chord length and radius?
You can use the cosine rule to calculate the central angle.
How do you calculate the root radius of an angle?
There is no such thing as a "root radious of a angle".There is no such thing as a "root radious of a angle".There is no such thing as a "root radious of a angle".There is no such thing as a "root radious of a angle".
Calculate a sector of a circle if the angle is 150 degrees and the radius is 13cm?
The area of the sector is: 221.2 cm2
How does one calculate arc length when given the radius and angle measure in degrees?
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.
How do you find the length of an arc in a circle?
You can measure it with a string. If you want to calculate it based on other measurements, you can multiply the radius times the angle, assuming the angle is in radians. If the angle is in degrees, convert it to radians first.

How do you draw an arc with a given length and known radius?
The length of an arc equals he angle (in radians) times the radius. Divide the length by the radius, and that gives you the ange. Measure out the angle on a protractor and draw the length of the radius at the begining and end of the angle. Then draw theportion of the circle with its center at the location ofthe angle and extending out to the radius.
