Result: Now you have calculated all three variables (A, B and C) for the General Form Linear Formula. Also note that the circle calculator will always display the raw results (out to 14 places) in the steps that will appear beneath the calculator. The gradient of a straight line can be found using the gradient calculator. All calculators have been tested to work with the latest Chrome, Firefox, and Safari web browsers (all are free to download). When the line is bent all the way, it wraps around the complete circle. Plugging our radius of 3 into the formula, we get C = 6 meters or approximately 18.8495559 m. Now we multiply that by (or its decimal equivalent 0.2) to find our arc length, which is 3.769911 meters. Click save settings to reload page with unique web page address for bookmarking and sharing the current tool settings, or click flip tool to reverse the tool function with current settings, Switch tool with the current settings for diameter, and calculate circle area, circle radius, sphere volume or sphere surface area instead. . Converting a circle's diameter to a straight length? For a better experience, please enable JavaScript in your browser before proceeding. This was a process that involved attempting to construct a square with the same area as a given circle within a finite number of steps while only using a compass and straightedge. d = Diameter (drop down ft, in, yd, cm, mm, m) It is the same as the perimeter of a geometric figure, but the term 'perimeter' is used exclusively for polygons.
