the radius of the base of a cylinder is 3 feet. is the volume of the cylinder a linear or nonlinear function of the height of the cylinder?

That would be a linear function

The volume of a cylinder is calculated by the product of area of the base times the height. It is expressed as:

V = pi x r^2 x h

Therefore, the volume is linearly related with the height of the cylinder. As the height increases, the volume increases as well. Hope this answers the question.

This is a rectangle

Step-by-step explanation:

2D shape with 4 right angles would be a rectangle because 2 sides are equal and the other 2 would be equal to give you 4 right angles
