In this demonstration I show how the volume of a cone is 1/3 the volume of a cylinder.

A shaped charge is a device capable of focusing the energy of an explosion in one point, this makes it capable of piercing many inches of steel.

Use these proven fraction shortcuts to save time and increase your understanding of fractions.7 shortcuts for solving fractions in record time

Example problems dividing rational exponents. (fractional exponents)The video covers the rules for dividing fractional exponents. Fractional exponents are also called rational exponents.

A hemisphere is sphere that has been cut in half. When you cut the sphere in half you are left with the great circle, plus half of a sphere. This fact can be used to find the area, and the volume of a hemisphere. The video works several example problems in which the area and volume of a hemisphere is calculated.

Use this shortcut to divide any number by 9 easily. Using this Math trick you divide any number by nine much easier than the traditional method.. The video works five examples.

If you need another method to learn how to divide then check out this video. This method involves using round numbers and subtraction in order to help you divide.

What are perpendicular lines or what is perpendicular? Well perpendicular are two lines that intersect at 90 degree angles. So let's look at a couple of examples of where we will see those. So we have two lines and they are intersecting at 90 degree angles, and I will label it with a little box that represents 90 degrees, and once we know this is 90 degrees we know the other three are 90 degrees because these are lines and lines have a degree of 180 so that would make all four of these 90...
