The resulting answer is written in radians, and can be converted to degrees by multiplying that number of radians by 180, then dividing by 3.14 (pi). (s/r) * (180 / 3.14) The circumference of a circle is found by using the formula 2 * 3.14r or 3.14d. To find the length of an...
In particular, the length of an arc of a circle of radius 'r' that subtends an angle θ at the center is calculated by the formula rθ × (π/180) if the angle is in degrees and if the angle is in radians, then the arc length is rθ. Let 's see how to derive these formula...
How to find the radius of a circle How can you prove a triangle's congruency in the case ASA, SAS, SSA, AAS? Can you use tricks to easily prove it? How to determine the midpoint of each line segment with the given endpoints
Explain how to find the distance from the center of circle to a chord. Chord A chord of a circle is a straight line that connects any two points of the circumference of the circle. The largest chord in the circle is the diameter of the circle, that is twice the length ra...

The circumference of a beach ball is 95 cm. How much air would it take to fill the beach ball completely? Answer and Explanation: The formula for the volume of a sphere is V = (4/3)(pi)(r^3), where r is the radius of the sphere. Theref...
In geometry, there are 360 degrees in a complete circle. But what if you're working with radians? How do you convert degrees to radians? Read on to find out! There are two key things to remember when converting degrees to radians. First, there are 2π radians in a complete circle....
This almost makes the plot I want. I just would like the radial circles labeled 10, 20, 30, and 40 on the left side of the plot. Also, why is the angle, th, in radians instead of degrees? Also, how to "label" the x axis. Something like "Foot...
This tutorial will demonstrate how to find the Great Circle Distance using an Excel formula. What Is Great Circle Distance? When dealing with the surface of a sphere, we use the Great Circle Distance to calculate the shortest distance between two points. The formula is: d = rcos-1[cosA....
The value of arctan 0 in degrees is 0 and the value of arctan 0 in radians is 0. This is because tan 0 = 0 when the angle is in radians or degrees. Learn more about finding the value of arctan 0 along with examples.
