Answer:
34.54 in (Answer C)
Step-by-step explanation:
The formula for the circumference of a circle whose radius is known is
C = 2πr.
Here, r = 5.5 and π ≈ 3.14, and so the circumference of the circle is
C = 2(3.14)(5.5 in) = 34.54 in (Answer C)
Answer:
15 times the first equation and -12 times the second equation
Step-by-step explanation:

------> first equation
------> second equation
Multiply the first equation by 15 both sides

-----> new first equation
Multiply the second equation by -12 both sides

-----> new second equation
Adds the two new equations
