To find the volume of a Cylinder, we would use this formula: V = πr^2h

Question

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

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

Answer 1

B. False; a cylinder is 3-dimensional with 2 of the dimensions being the same.

To find the volume of a cylinder, you need the radius (r) of the base and the height (h). Since the base is a circle, the radius is the only dimension required for the circular cross-section, which makes it just two different dimensions (the radius and the height) rather than three.
