Cylinders

[Page 19 of 32]

A cylinder is a uniform solid with two opposing circular faces. The surface area between the faces is the lateral area. This lateral surface area of a cylinder is equal to the circumference of the cylinder times the distance between the faces.

To find the volume of a cylinder, find the area of one of its circular faces, and multiply it by the distance between the faces.

Task: If a cylinder has a radius of 8, and the distance between its circular faces is 20, what is its volume? Type in your answer and then click Continue.

Volume = 1280

Task: If a cylinder has a radius of 2 and the distance between its circular faces is 10, what is its lateral surface area? Type in your answer and Area =
