Answer:
79.617...
Step-by-step explanation:
When you are trying to find the circumfrence you do c=πd
So to find the diameter you reverse it
Since you already know the 250 feet you divide it by π
You then get 79.6
You can calculate the difference/vector of both points:

then calculate the magnitude/length like pythagoras
Answer:
x = 12
Step-by-step explanation:
5x + 15 = 75
-15 -15
5x = 60
x = 12
