๐ Topic Summary
A cylinder is a 3D shape with two parallel circular bases connected by a curved surface. The radius is the distance from the center of a circle to any point on its edge. The diameter is the distance across the circle through the center (twice the radius). The height is the perpendicular distance between the two circular bases. Identifying these components is key to calculating a cylinder's volume and surface area.

A cylinder has two circular _____. The _____ is the distance from the center of the circle to its edge. The ______ is twice the radius. The _____ is the distance between the two bases.
๐ค Part C: Critical Thinking
Imagine you have a cylindrical can of soup. If you double the radius of the can, how does that affect the amount of soup it can hold (the volume)? Explain your reasoning.
