ANSWER
The area of the base is 14.5π in²
EXPLANATION
The volume of a cylinder is given by
Or
V=Bh
It was given that the volume of the cylinder is 174π in³.
The height was given as 12 inches.
We substitute to get,
174π=12B
Divide both sides by 12 to get:
B=14.5π in²
Hence the area of the base is 14.5π in²
He drank 48 quarts
the formula to get that answer is multiply the volume value by 4.
Answer:
720
Step-by-step explanation:
With Gulliver's Travels in the first spot and A Tale if Two Cities in the last spot, there are 6 empty spots in between. Any of 6 books can go in the second spot, and then there 5 books left to pick from for the third place. That leaves 4 books to choose from for the next space and then 3 and then 2 and then one last book left to fill in (in front of Tale of Two Cities) since there's so many choices, we actually multiply to calculate how many different versions of the shelf we can get.
6•5•4•3•2•1 is 720 ways this can happen.
The mathy way to write that multiplication is 6! (Yes, an exclamation mark is a math symbol too, it is called factorial)
