In this video you will see a demonstration of the volume of a cylinder compared to the volume of a cone.I filled up three cones and poured them into an equal sized cylinder.Watch what happened.
In this video you will see the formulas for area and perimeter visually presented. The shapes include a rectangle,square,circle, parallelogram,triangle, and a trapezoid.
In this video you will learn how to find the area of composite figures. In this video the composite figures are composed of rectangles,triangles, and semi-circles.
In this video you will learn how to subtract mixed fractions.I like to convert mixed fractions to an improper fraction, and then subtract the improper fractions.
In this video you will learn how to find the volume and surface area of a hemisphere.A hemisphere is half of a sphere.Think of cutting an orange exactly in half.Each half will be a hemisphere.
In this video you will learn how to convert units of measure using dimensional analysis.For example, 10,000 feet per hour equals how many miles per hour?
In this video you will learn how to subtract mixed numbers two different ways. Method one uses regrouping, and the second method uses converting the mixed number to an improper fraction then subtracting.
Euclidean Geometry is the Geometry of flat space.It is based on the work of Euclid who was the father of Geometry.He proposed 5 postulates or axioms that are the foundation of this mathematical branch of Geometry.The 5 postulates are,It is possible to draw a straight line from any point to any point.
In this video you will learn how to solve one step equations with decimals.The video works one problem with division,one with multiplication, and one with addition and subtraction of decimals.
In this video you will learn how to solve basic one step equations that contain fractions.The video contains two examples in which you have to divide the fractions, and one in which you multiply the fractions.
Video covering how to set up a Venn diagram. The video covers how to draw the diagram and then look at a set of data and place the data in the correct part of the Venn diagram. The sample problem is as follows.
Factoring a trinomial-In Algebra a trinomial is a polynomial with three terms. Use this method I call the "rainbow method" to help with your factoring.
The video reviews how to find the radius of a sphere given the volume.The question that is solved is,Find the radius of a sphere with a volume of 72 meters squared.The volume formula is 4/3 pi r cubed.In order to solve for the radius you have to undo the formula.
Heron's formula is used to find the area of a triangle when the altitude is not known. The first part of Heon's formula is calculating "S" The next step is to take "S" and plug it into the area formula. The video works out an example problem. Heron's formula looks complicated but is is really pretty easy to use.
