Answer:
Diameter: Circumference 
Step-by-step explanation:
Because this is Pi, which is the same for any circle.
 
        
             
        
        
        
Assuming the shape is a piece of a circle, you can determine the ratio of the shape to a full circle. A full circle will have 360 degree but this shape is only 40 degree. Then the ratio would be: 40/360= 1/9 full circle.
Then, using the circle area formula, the area of the 1/9 circle would be: 
full circle area= pi * r^2
full circle area= 22/7 * 6^2
full circle area= 792/7
1/9 full circle area= 792/7*9= 88/7 = 12.57
        
             
        
        
        
Answer:
4x² + 20x - 2
Step-by-step explanation:
To evaluate (c ○ d)(x), substitute x = d(x) into c(x)
c(x² + 5x)
= 4(x² + 5x) - 2
= 4x² + 20x - 2
 
        
             
        
        
        
11/12 and 1/8
we only need to look at the denominators which is 
12 and 8
12 24 36
8   16 <span> 24
</span>so the LCD is 24
        
             
        
        
        
Your answer is -2 1/12. :)
