A diagram of Eric's pool is shown below. He plans to fill his pool to a depth of 5 feet with a garden hose that has an 60ft^3 per hour flow rate. How many hours will it take to fill the pool?

2,576.5

Step-by-step explanation:

The Volume of a Cylinder  =   π • r² • height

radius = 13.5 feet

volume = PI * 13.5^2 * 4 feet (the problem states it is to be filled to a depth of 4 feet)

volume = PI * 182.25 * 4

volume = 2,290 cubic feet

The hose delivers 80 cubic feet per hour so it will take:

2,290 / 80 = 28.625 hours

The volume of the pool is:

volume = PI * 182.25 * 4.5

= 2,576.5 cubic feet

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.
