You haven't specified which problem you want to focus on first. It's not realistic to post a whole page of problems at once and ask someone else to help you with all of them.
I'll focus on the first problem.
What is the circumference of a circle with radius 14 feet? Use pi =3.14.
The formula for "circumference of a circle" is C = 2 pi r.
If the radius of this particular circle is 14 feet, then C = 2 (3.14) (14 feet).
Multiply that out, please.
