Hello There!
To find a cylinder, we use the formula Pi*radius “squared” *height
First, let’s put in our values. Our radius is 5 but in our formula, we have to square 5 so we get a product of 25.
Then we multiply 25 by 9 because you will see in our formula we have to multiply by the height. 25*9 equals 225
Now, we are putting our value in terms of pi so our answer would be 225
