What is the definition of a cylinder?

Back

A cylinder is a 3-D shape with two parallel circular bases connected by a curved surface, having 3 faces, 2 edges, and 0 vertices.

Front

How many faces does a sphere have?

Back

A sphere has 0 faces, 0 edges, and 0 vertices.

Front

What is the difference between edges and vertices in 3-D shapes?

Back

Edges are the line segments where two faces meet, while vertices are the points where edges meet.

Front

Can you name a 3-D shape that has only one curved surface?

Back

A cylinder and a sphere both have one curved surface.

Front

What is the formula for the volume of a cylinder?

Back

The volume of a cylinder is calculated using the formula V = πr²h, where r is the radius of the base and h is the height.
