Here's the solution ~
As we know, we can calculate the circumference of a circle in terms of its diameter as :

where, c = circumference and d = diameter
And also, circumference of circle is terms of radius (r) is :

Answer:
1. (-125 a - 5.75) x + b c (605 x - 550 x^2) + 10.75
2. -125 a x + x (-550 b c x + 605 b c - 5.75) + 10.75
3. 0.25 (-500 a x - 220 b c (10 x - 11) x - 23 x + 43)
Step-by-step explanation:
The answer should be 3.5 pounds. You divide 56 by 16 to get your answer
The answer is 13
If R=4 the the equation would be 4+9 which equals 13.
21:3
9:3
3:1
there all a 3:1 ratio
