Do you mean how you can tell between an area formula and a volume formula? Well usually like on a reference sheet it says the shape and the letter a or v, a representing area and v representing volume. I hope this helps, if it doesn't please tell me in the comment section
Answer:
Height of cylinder is
.
Step-by-step explanation:
Diameter of cylinder, D = 6 feet
Relation between Radius, R and diameter, D is given by:

So, radius, R =
feet
Let height of cylinder be
feet.
Formula for volume of cylinder is given by:

Where, R is the radius of base of cylinder
and H is the height of cylinder
We are given that,

Using formula for volume, 

Hence, Height of cylinder is
.
