A cylindrical shaped swimming pool has a diameter of 30 feet and a water height of 4.5 feet. How many cubic feet of water is contained in the pool? Use 3.14 for pi. Round your answer to the nearest cubic foot.

Answer: A
Step-by-step explanation:
The question asks about how much space the cylinder can hold. That's how i know they are really asking for the volume of the cylinder.
Next, the volume of a cylinder is V= πr²h
R is the radius
h is the height
π= 3.14 (in this question).
We know that the diameter is 30, and that the radius is always 1/2 of the diameter. To find the radius, find 1/2 of 30. Whenever you see something of something, just turn the "of" into the multiplication sign. So just do 1/2 x 30= 15.
R= 15
H= 4.5
Pi= 3.14
Now we can plug into the formula:
Using pemdas, do exponents first. Then multiply from left to right.
V= πr²h
V= 3.14x15²x4.5
V= 3.14x225x4.5
V= 706.5x4.5
V= 3,179.25
3,179.25 rounds rounds to just 3,179 because first you round the .25 to point 3, and because 3 is under 5, it rounds down. The answer is A
Hope this helps :)) Also brainliest would be appreciated, I worked pretty hard on this :D
