For a complete lesson on volume of a cone, go to http://www.yourteacher.com - 1000+ online math lessons featuring a personal math teacher inside every lesson! In this lesson, students learn that the formula for the volume of a cylinder is pi times radius squared times height, so the volume of a cylinder that has a radius of 10 feet and a height of 40 feet is pi times 10 squared times 40, or pi times 100 times 40, or 4000 pi cubic feet. And since pi = 3.14, 4000 pi cubic feet can also be written as 4000 times 3.14, or 12,560 cubic feet. Students also learn that the formula for the volume of a sphere is 4/3 times pi times radius cubed, and the formula for the volume of a cone is 1/3 times pi times radius squared times height.

why are the 1/3 and 18 cm cross canceled?

@Qermaq Oh I thought you were saying that 8cm2 is equivalent to16cm2, but 8cm x 8cm (8cm2) = 16cm. Sorry!
Qermaq (November 30, 1999 at 12:00 am)
@RabidMrDog 8cm x 8cm = 64cm^2 because you aren't talking about linear cm's anymore, you're talking about area.
