23.5-6 Volume of a Cylinder

Step 1
Measure the height (h) of the cylinder. Height is sometimes referred to as the length.

Step 2
Measure the radius (r) of the cylinder. Radius is the distance from the outer edge to the center of the circle.

Step 3
Square the radius. (Multiply the radius by itself.)

Step 4
Mulitply the product (radius squared) from step 3 by pi.
Step 5
Multiply the product from Step 4 by the height

Step 6
Write you answer in the proper cubic unit of measurement.

23.4 volumes of Pyramids

The area of a pyramid can be found by using the following equation:

V= 1/3Bh, where B = l x w

This is read as "volume equals one-third base times height." Watch the following video to see why

23.2 Estimate and find Volume

Things to remember:

• Volume is given in cubic units - a little three above the units
• multiply the area of the base (length times width for rectangles - 1/2 lenght times width f or triangles) times the height to find volume
