1) c= 3.5cm × 22/7
 c= 77cm/7 = 11cm
2) c= 2×3.14×5cm
 = 6.28× 5cm
 =31.4cm
3) L=180/360 × 22/7 × 3cm
 = 1/2 × 22/7 ×3cm
 =4.71 cm
4) c=12cm ×3.14
 =37.68cm
5) c = 4.5cm × 3.14
 =14.13cm
6) c = 6.7cm × 3.14
 = 21.038cm
 
        
             
        
        
        
Y=-3/2x+4 
The slope is -3/2, since Kerry traveled three feet and only went down 2. 
The y intercept is 4, since she started four feet above the origin
        
             
        
        
        
Answer:
A=1, B=3, C=15
Step-by-step explanation:
I think that 
1(3x+3)=15
3x+3=15
3x=12
x=4
