Answer: The rational expression that is needed is z^5/8.
In the problem, we are starting with 4z^5/7 and multiply by something. Then, we have z^10/14.
First, let's deal with the variables. We go from z^5 to z^10, so we had to multiply by z^5.
Second, our fraction went from 4/7 to 1/14, the missing factor would be 1/8 because 4/7 times 1/8 equals 1/14.
Answer:
1st Circle
Radius = 9
Diameter = 18
Circumference = 2 ×
× r = 2 × 3.14 × 9 = 56.52
2nd Circle
Radius = 14
Diameter = 28
Circumference = 2 ×
× r = 2 × 3.14 × 14 = 87.92
