Calculating a circle's arc length, central angle, and circumference are not just tasks, but essential skills for geometry, trigonometry and beyond. The arc length is the measure of a given section of a circle's circumference; a central angle has a vertex at the center of the circle and th...
Notice the angle formed by the two radii. Divide this angle by 360 to find out what portion of the circle it represents. For instance, if the angle is 45 degrees, divide 45 by 360 to get 0.125. Find the area of the circle by squaring the radius and multiplying that by 3.14 (pi)....
The formula for the surface area of a circle isA= π_r_2, whereAis the area of the circle andris the radius of the circle. An Introduction to Pi In order to calculate the area of a circle you'll need to understand the concept of Pi. Pi, represented in math problems by π (the s...
To construct a spiral, make a right angle with sides A and B of equal length, which becomes the "1" value. Next, make another right triangle using side C of your first triangle – the hypotenuse – as side A of the new triangle. Keep side B the same length at your chosen value of...

You want to use the elliptical Arc command. Unfortunately for you, this requires you to specify the Cartesian coordinates (x, y) of the start and end points rather than the polar coordinates (radius, angle) that you have, so you have to do some math. Here's a JavaScript function which...

A‘rhumb line’ (or loxodrome) is a path of constant bearing, which crosses all meridians at the same angle.Sailors used to (and sometimes still) navigate along rhumb lines since it is easier to follow a constant compass bearing than to be continually adjusting the bearing, as is needed ...
