Answer:

Step-by-step explanation:
In the attached diagram, circle R is shown. Line segments QR and SR are radii and QR = SR = 18 units.
The measure of the central angle QRS is 
1. Find the area of the whole circle:

2. Note that the whole circle is determined by the full rotation angle with measure  radians. So,
 radians. So,

So, write a proportion:

Cross multiply

 
        
                    
             
        
        
        
24x11 = 264
264 / 8 = 33
a = 33
