Answer:
37.68
Step-by-step explanation:
C(circumference)= 2pi r
If the diameter is 12, the r adius is 6
plug into equation 
2(pi)(6)
=12pi
=37.68
 
        
             
        
        
        
You would divide 121 by 8. 
121 / 8 =  15.125 So she did about 15 sit ups in a minute. Hope this helps!
 
        
                    
             
        
        
        
12%= 0.12 = 12/100 = 108/900
1/10 = 90/900
2/9 = 200/900
108/900 + 90/900 + 200/900 = 398/900 used
900- 398 = 502
502/900 = 251/ 450
251/450 × 450 = 251
