Which of the following has 2 parallel bases that are not polygons?

a. Cone
b. Prism
c. Pyramid
d. Cylinder

Eliminate those that have polygon as bases.

Then choose from the remaining responses that have two parallel bases.
Post what you've got.

I'm 100% sure it's .... Pyramid

The option that has two parallel bases that are not polygons is the (d) Cylinder.

To determine which of the given options has 2 parallel bases that are not polygons, let's analyze each shape:

a. Cone: A cone has a circular base and a curved surface that connects the base to a single point called the apex. Since the base is circular (a polygon), a cone does not have 2 parallel bases that are not polygons.

b. Prism: A prism has two parallel bases, which are polygons, connected by rectangular or triangular faces. Therefore, a prism does not have 2 parallel bases that are not polygons.

c. Pyramid: A pyramid has a polygonal base and triangular faces that connect the base to a single point called the apex. Since the base is polygonal (a polygon), a pyramid does not have 2 parallel bases that are not polygons.

d. Cylinder: A cylinder has two circular bases that are parallel to each other, and the lateral surface is curved. Neither of the circular bases are polygons, so a cylinder has 2 parallel bases that are not polygons.

Therefore, the correct answer is option d. Cylinder.
