Jason is filling his circular pool with water. the diameter is 14 feet. if it takes an hour for the water to rise 6 inches, how long will it take to fill the pool 4 feet?

Well, the diameter doesn't matter in this problem because we allready know how fast, and how much the pool is filling. So, 6 inches is half of a foot, because 1 foot = 12 inches, and six is half of 12. If it take 1 hour for the pool to fill 1/2 of an foot, than it takes 2 hours for a full foot. Next, we multiply 2 hours, by 1 foot, and convert the 1 foot, to 4 feet. Which means to figure out the number of hours, we have to times 2 hours by 4 feet. And that is 8. 
So the answer is: 8 feet.
I hope this helped! Please mark brainliest!

-1 to the power 3 is -1 itself
so, -1-3=-4
since modulus of-4,the answer becomes 4
