Question

greta makes a slice through a three-dimensional object parallel to the base the cross section is a circle. What three dimensional shapes might greta have cut?

Answer 1

A. Cylinder

C. Cone

Explanation:

Both a cylinder and a cone are three dimensional shapes that contain a circle as the base. If a cross section is made parallel to the base, that means that it should have the same shape as the base. Since a pyramid and cube both have straight edges, it would not be possible to form a circle from a parallel cut to the base, so the only options are cylinder and cone.

Answer 2

A. Cylinder.

C. Cone.

Explanation:

Notice that the cross section is parallel to the base. So, if the cross section is a circle, then the base is also a circle.

Then, we just need to find all figures that have a circle at the bottom. The figures are a cylinder and a cone.

Therefore, the right answers are A and C.
