Question

Find the length (in inches) of the arc on a circle of radius r intercepted by a central angle theta. (Round your answer to two decimal places.)

r = 13 inches, theta = 300°

Answer 1

68.07.
To get this answer we need to find the circumference of the circle and then take 300/360 of that (360 degrees in a circle). The circumference is 2 pi r. R is radius which is 13. 13x2=26. 26xpi≈81.68 (when rounded to nearest two decimal places). 300/360x81.68≈68.07
