Step-by-step explanation:
The volume of a cylinder can be calculated with the following formula:

Where "r" is the radius and "h" is the height.
The volume of a sphere can be found with this formula:

Where "r" is the radius.
Then, volume of the empty cylinder is:

And the volume of the ball is:

Finally, you need to subtract them in order to calculate how much water is in the cylinder:

9514 1404 393
Answer:
b, d, c, a, e
Step-by-step explanation:
A formula should always come with a definition of the variables it uses. Here, you're supposed to somehow magically figure out what the variables are.
A = P(1 +r/n)^(nt)
A is the amount of the investment of principal P after t years, compounding annual rate r n times per year.
__
Then your blanks get filled like this:
1. A -- b the value
2. P -- d the principal
3. r -- c the annual interest rate
4. n -- a number of times compounded per year
5. t -- e number of years
