Can anyone help me find the answer and process of number 1?

Answer:
Step-by-step explanation:
I used the equation [tex]V=\pi r^2h[/tex]
[tex]\pi r^2[/tex] represents the base and since the base is already given, we will plug that in instead.
here is what solving this would look like:
1. plug given information into the equation
[tex]V=(75)(9)[/tex]
2. multiply 75 by 9
[tex]V=675[/tex]
