Maks123456 Posted March 5, 2014 Report Share Posted March 5, 2014 (edited) Start by what you know.The arc length is found by l = r(theta)L = 24r and theta are unknown so24 = r(theta)The sector area equals to A= 1/2 (r^2(theta))A= 180 cm180 = 1/2(r^2(thetta)360 = r^2(theta)Then, using the arc length formula, you can say that r = 24/thetaSubstitute this into the Sector area:360=(24/theta)^2(theta)solve using Calculator.//this is what i am guessing anyways Edited March 5, 2014 by Maks123456 Reply Link to post Share on other sites More sharing options...
