The arc length of the semicircle is 5π units 
<h3>Calculating length of an arc</h3>
From the question, we are to calculate the arc length of the semicircle 
Arc length of a semicircle = 1/2 the circumference of the circle 
∴ Arc length of a semicircle = 1/2 × 2πr
Arc length of a semicircle = πr 
Where r is the radius
From the given information, 
r = 5 
∴ Arc length of the semicircle = 5 × π
Arc length of the semicircle = 5π units 
Hence, the arc length of the semicircle is 5π units

Answer:
(x-6) (x-4)
Step-by-step explanation:
 x^2 - 10x + 24
What 2 numbers multiply to 24 and add to -10
-6*-4 = 24
-6+-4 = -10
(x-6) (x-4)
 
        
             
        
        
        
Answer: 1682 
(45 x 36) + 62
 1620 + 62 = 1682 
        
             
        
        
        
For this use the law of sines:


cross-multiply:
16×sin (J) = 11×0.97
sin(J) = 10.72/16
sin(J) = 0.67
