A right cylinder-shaped water tank is used to supply water to a reservoir. If the cylinder has a diameter of 16 feet and a height of 22 feet, what is a reasonable estimate of the maximum amount of water the tank can hold? (Use π≈3.14)

9514 1404 393

  4421 cubic feet

Step-by-step explanation:

The volume of a cylinder is given by ...

  V = πr²h

where r is the radius (half the diameter), and h is the height.

Using your numbers, the cylinder volume is ...

  V = (3.14)(8 ft)²(22 ft) ≈ 4421.12 ft³

The maximum amount of water the tank can hold is about 4421 cubic feet.

just needed some points but try socratic

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
