Answer:
Step-by-step explanation:
-3 / 1 8 9 -18
-3 -15 18
_______________
1 5 -6 0
The remainder here is 0 and the quoitient is 1x^2 + 5x - 6.
You need to find circumference, so you would multiply the diameter by pi. So your answer is 212pi feet or 666.02 feet
If you need the sum than here is an equation for it 7x3= 21
