Answer:
10
Step-by-step explanation:
1x2x2.5=5 
5/0.5=10
 
        
                    
             
        
        
        
M = (y2 - y1) / (x2 - x1)
1/4 = (5-3) / (r +4)
1/4 = 2/ (r + 4)
Cross multiply 
2*4 = r + 4
8 = r + 4
Subtract 4 from both sides 
4 = r
CHECK
(-4,3)(4,5)
m = (5-3)/(4--4) = 2/8 = 1/4
        
             
        
        
        
Answer: 7.1 yd
Step-by-step explanation:
the formula for arc length is 2πr(x/360),  x being the central angle
input the values, so the equation would be 2π9(45/360), which equals 7.1
