Best ResponseYou've already chosen the best response.1use the proportion : 150/360 = arc AB/circumference circle 150/360 = 9π/2πr 5/12 = 9/2r solve for r

Best ResponseYou've already chosen the best response.09? = 2?r(150/360) r = 10.8 unites 2? = (1/2)(x)3^2, where x is the measure of ?COD in rad. x = 4?/9 rad = 80 degrees im for sure
