Arc and Angle Measures The measure of an arc can be found by dividing that arc's length (s) by the circle's radius (r). (s/r) = (arc's length / circle's radius) The resulting answer is written in radians, and can be converted to degrees by multiplying that number of radians by...
Hello, I am creating some Engraving on a part using the 'contour' toolpath with a line that is drawn on a arc. Is there a way I can find out what the radius is of the toolpaths points extent at the lowest point (smallest radius) in the post? basically I am adding cycle 225...

The stadium's racecourse had an unusual circular arc starting line, and measurements along this arc form the basic data sets of Rorres and Romano (SIAM Rev. 39 : 745–754, 1997). Here we are interested in finding the center and radius of the circle that defined the starting line arc. ...

The central angle of an arc can be found by dividing the arc length by the radius of the circle and converting it to degrees. Can you find the length of an arc without knowing the central angle? Yes, the length of an arc can also be calculated by knowing the radius and the...
