Answer:
Divide the central angle in radians by 2 and perform the sine function on it. Divide the chord length by double the result of step 1. This calculation gives you the radius. Multiply the radius by the central angle to get the arc length.
 
        
                    
             
        
        
        
Answer:
y = 7 
Step-by-step explanation:
Use the given ordered pairs to find a and b
Using (0, 7 ), then
7 = a  (
 (  = 1 ), thus
 = 1 ), thus
a = 7
y = 7 
Using (5, 1701 )
1701 = 7  ( divide both sides by 7 )
 ( divide both sides by 7 )
243 =  ( take the fifth root of both sides )
 ( take the fifth root of both sides )
b = ![\sqrt[5]{243}](https://tex.z-dn.net/?f=%5Csqrt%5B5%5D%7B243%7D) = 3 , thus
 = 3 , thus
y = 7  
 
 
        
             
        
        
        
The answer is C) 24.
24 + 19 = 43.
43 - 24 = 19.
