Which solid figures have at least 1 circular base?


A) cylinders and cones

B) cones and cubes

C) spheres and cones

D) cylinders and spheres

The correct answer is option A) cylinders and cones.

To determine which solid figures have at least one circular base, we need to have a basic understanding of the shapes of different solid figures.

A cylinder is a three-dimensional shape that has two circular bases parallel to each other. The bases are connected by a curved surface. So, a cylinder has at least one circular base.

A cone is also a three-dimensional shape that has a circular base and a single vertex at the top. The curved surface of a cone connects the vertex to the circular base. Therefore, a cone also has at least one circular base.

On the other hand, spheres and cubes do not have any circular bases. A sphere is a perfectly round three-dimensional object, while a cube has six square faces.

Hence, the solid figures that have at least one circular base are cylinders and cones.

a cube does not

a sphere does not (base is a point)
