We have given that area of the sector is $\frac{5}{18}$of the area of the circle. Therefore, area of the sector =$\frac{5}{18}$xx area of the circle $\therefore$ $\theta$/360xxpir^2=$\frac{5}{18}$xxpir^2 Now we will simplify the equation as below, $\theta$/360=$\frac{5}{18}$ Now we will multiply both sides of the equation by 360, $\therefore$ $\theta$=$\frac{5}{18}$xx360 $\therefore$ $\theta$=100 Therefore, sector angle is $100^\circ$
