Cylinder Notes Date: A cylinder is like the right prisms with which we have been working all week, except that the bases of a cylinder are circles. The volume and total area can be calculated in a very similar manner. In a cylinder, the formula for Volume is exactly the same. Multiply the area of the base by the height. In this case the base is a circle. Recall that the area of a circle is calculated by using A =. The Lateral Area and Total Area is calculated in a similar manner. However we must replace perimeter of base with, use Therefore, to find the Total Area and Volume of a cylinder you must still calculate the same three pieces of information: 1. of the base 2. of the base 3. Height of the object given Example 1 Find the Total Area and Volume of the given cylinder. Radius Area of Base Circumference of Base Height Volume 10in Lateral Area 4in Total Area - page 11
