An illustration shows a right circular cylinder with an axis measuring 5 centimeters and diameter measuring 10 centimeters.
What is the height of the cylinder shown?
The diameter of a right circular cylinder is twice the radius. Thus, the radius of the cylinder is 10 centimeters / 2 = 5 centimeters / 2 = 2.5 centimeters.
The height of a cylinder is the distance between the two bases. Since the axis of the cylinder is the height, the height is equal to 5 centimeters.
