First you need to figure out the slope:
y2-y1/x2-x1=(1+5)/(-5-7)=-1/2
y+5=-1/2(x-7)
y=-1/2x-3/2
circumference = diameter x PI
3300 *3.14 = 10,362 feet
Answer:
C x 34 or 34c
Step-by-step explanation:
There isn't really a way to show work or really an answer unless you have a value for C but I hope this helped anyway.
