So multiply both sides by 18 pi. Create a new family you can use the Generic Model template or use an existing family. One is in the top half and one is in the bottom half of the circle but since we are interested in how high the arc is above the line we only care about the top half.
Well same exact logic-- the ratio between our arc length a and the circumference of the entire circle 18 pi should be the same as the ratio between our central angle that the arc subtends so 350 over the total number of degrees in a circle over 360.
Learn how tosolve problems with arc lengths. Arc Length Formula if th is in degrees s 2 p r th360 Arc Length Formula if th is in radians s ϴ r. You will learn how to find the arc length of a sector the angle of a sector or the radius of a circle. So if you divide the measured arcs degree by 360 you discover the fraction of the circles circumference that the arc makes up.
