Answer:
308
Step-by-step explanation:
 
        
                    
             
        
        
        
87 / 114 = x / 9918....87 people to 114 = x people to 9918
cross multiply
(114)9x) = (87)(9918)
114x = 862866
x = 862866/114
x = 7569 <=== 
        
                    
             
        
        
        
Area inside the semi-circle and outside the triangle is  (91.125π - 120) in²
Solution:
Base of the triangle = 10 in
Height of the triangle = 24 in
Area of the triangle = 
                                 
Area of the triangle = 120 in²
Using Pythagoras theorem,




Taking square root on both sides, we get
Hypotenuse = 23 inch = diameter
Radius = 23 ÷ 2 = 11.5 in
Area of the semi-circle = 
                                       
Area of the semi-circle = 91.125π in²
Area of the shaded portion = (91.125π - 120)  in²
Area inside the semi-circle and outside the triangle is  (91.125π - 120)  in².
