To find the volume of a Cylinder, we would use this formula: \large V=\Pi r^2h.

We would need to know 3 different dimensions to find the volume.

True; a cylinder is 3 dimensional with 3 different dimensions
False; a cylinder is 3 dimensional, with 2 of the dimensions being the same.

Answer: False; a cylinder is 3 dimensional, with 2 of the dimensions being the same.

Step-by-step explanation:

Think of a 3D rectangular block. To find the volume we compute length*width*height. Therefore, we need 3 pieces of info to find the volume of the block.

However, a cylinder has its "length" and "width" as the same thing (both equal to the diameter). Effectively we have 2 unique pieces of info that is enough to find the volume of the cylinder.

Side note:

radius = (diameter)/2
