Question 951533: In a circle of radius 3m the area of a certain sector is 20m^2 find the degree of the measure of the central angle Answer by lwsshak3(11628) (Show Source):
You can put this solution on YOUR website! In a circle of radius 3m the area of a certain sector is 20m^2 find the degree of the measure of the central angle
area of a sector=1/2 r^2(theta), r=radius, central angle theta in radians
central angle=2*area/radius^2
theta=2*20/3^2=40/9≈4.44 radians
