Learn how to find the volume of cylinders in this engaging lesson. Discover the formula V = B * h, where B is the base area and h is the height. A cylinder consists of two parallel, congruent circular bases, and its volume can be calculated using the radius of the base (r) with the formula B = πr². Work through examples, including calculating the volume of a cylinder-shaped coffee can, and complete guided practice problems for mastery. Prepare effectively for your mid-test with the provided homework exercises.

What you will learn! How to find the volume of cylinders.
What you really need to know! A cylinder is a solid figure that has two congruent, parallel circles as its bases. The volume V of a cylinder with radius r is the area of the base B times the height h.
Height h Base B = r2
Example 1: Find the volume of the cylinder. Round to the nearest tenth. 5.5 cm 9 cm
Example 2: Find the volume of a cylinder-shaped coffee can that has a diameter of 3 inches and a height of 6 inches.
