I feel like it isn't that easy...and that is incorrect...

11. Describe the relationship of input and output values for composite functions.

12. Explain how you know if a radical expression is in simplest form.

Idk how it isn't showing for you

13. How can you tell if radicals are like radicals?

14. Is the inverse of a function always a function? Explain.

wooo awesome!

The formula for volume of a cylinder is:

\(\Pi r^2h\)

Plug in numbers:

\(\Pi 2^25\)

The radius is half the diameter.

Now 2^2= 4

4*5=20

20*3.14=62.8

62.8 rounded to the nearest whole number is:

63

Thank you ^-^ I ended up getting the answer.
