4. I have a small circular swimming pool in my backyard for my grandkids. Last weekend, I set it up and bought chlorine to put into it. The directions on the bottle said to put in 16 fluid ounces of chlorine per 10,000 gallons of water. Of course, our pool holds a lot less water than 10,000 gallons, so I needed to figure out the correct amount of chlorine to put into it. The pool is 8 feet in diameter, and the height of the water was 36 inches. I know that the volume of a cylinder is V = (pi)(r^2)h , where r is the radius of the cylinder, and h is the height. I Googled to find that there are 231 cubic inches in a gallon of water. How many fluid ounces of chlorine did I need to put into the pool? (Round your answer to the nearest tenth of a fluid ounce
