4. The pool’s diameter is 24 ft across with 52 in high walls.
You are putting in an above-ground swimming pool. You want to use the same place each year so you are going to make a sand area that will be the consistent place for the pool.
The pool’s diameter is 24 ft across with 52 in high walls.
1. Your home owners association says that you have to get permission from your neighbors if the pool is bigger than 500 sq. ft. Do you need to get permission from your neighbors? Why or why not? Prove it with math.

5. The pool’s diameter is 24 ft across with 52 in high walls.
Picture from the internet.
The pool’s diameter is 24 ft across with 52 in high walls.
2. You want the sand area to be 1 foot wider than the pool all the way around. You were planning on digging down about 2 inches for the sand to go into like the picture you found on the internet. Each 50 lb bag of sand will cover about 3 ft² at 2 inches deep. If you order at least 100 bags you get free delivery. Will you be paying for delivery? Why or why not? Prove it with math.

6. The pool’s diameter is 24 ft across with 52 in high walls.
3. Use the above advertisements to figure out which type of sand is a better deal. You have a 15% discount coupon for Quickrete All-Purpose Sand, but not for the Play Sand. Which is the better deal? Prove it with math.

7. The pool’s diameter is 24 ft across with 52 in high walls.
4. Use the above advertisements to figure out how much the project is going to cost with tax. Remember, you have a 15% discount coupon for Quickrete All-Purpose Sand. And, the tax rate is 9.1%. Prove your answer with math.

8. The pool’s diameter is 24 ft across with 52 in high walls.
5. One website suggested using a square pad (see picture below) under the round pool because it would be easier to measure, build, and it provides a place for a ladder. You still want one foot from the side of the pool to the edge of the pad. What is the smallest square that you could put under the pool? How does that change your calculations? Which would you choose and why?
