Casey was at the surface of a swimming pool and recorded the following two measurements, in feet, on a number line: −8, which represents the depth of water in the swimming pool +7, which represents the height of the slide at the pool part a: what does 0 represent in this situation? (3 points) part b: describe the height of the slide in relation to 0 in the situation. (3 points) part c: casey held a pole in the swimming pool. the bottom of the pole was at a depth of 2 feet. how should casey mark the level of the bottom of the pole on the number line? explain how you determined this. (4 points)

Part A.

Since the value of – 8 ft refers to the depth of the water, then 0 must refer to the surface of the water in the pool. Or to look it the other way, 0 is the boundary of the water in the pool and the air in the surrounding.

Part B.

Since the height of the slide is + 7 feet, then this means that the top of the slide is 7 feet from the surface of the water in the pool.

Part C.

Since 2 feet of the pole was submerged in the water (2 feet is under the surface of the water), then Casey should mark the level of the bottom of the pole as -2.

step-by-step explanation:

circumference divided by 3.141592654 then timesthe radius twice

what level of math? also i don't need to be paid if i can you.
