Cylinder Facts
Notice these interesting things:

A wooden cylinder

An object shaped like a cylinder is said to be cylindrical.

Oblique Cylinder

When the two ends are directly aligned on each other it is a Right Cylinder otherwise it is an Oblique Cylinder:

Surface Area of a Cylinder

The Surface Area has these parts:

Which together make:

Surface Area = 2 × π × r × (r+h)

Example: h = 7 and r = 2

Try it yourself: cut some paper so it fits around a cylinder, then unwrap and measure it.

It will be h high and (the circumference of a circle) long:

Side area =
2 π rh

Don't forget the two end bits:

Total Surface Area
= 2(πr ²) + 2πrh
= 2πr(r+h)

Volume of a Cylinder

To calculate the volume we multiply the area of the base by the height of the cylinder:

And we get:

How to remember: Volume = pizza

Imagine you just cooked a pizza.

The radius is "z", and the thickness "a" is the same everywhere ... what is the volume?

(we would normally write "pi" as π, and z × z as , but you get the idea!)

Play with it here. The formula also works when it "leans over" ( oblique) but remember that the height is always at right angles to the base:

And this is why:

The stack leans over, but still has the same volume

Volume of a Tank

Learn how to find the volume of a partly filled horizontal cylinder like this one:

Volume of a Cone vs Cylinder

The volume formulas for cylinders and cones are very similar:

So a cone's volume is exactly one third ( ) of a cylinder's volume.

In future, order your ice creams in cylinders, not cones, you get 3 times as much!

Like a Prism

A cylinder is like a prism with an infinite number of sides, see Prism vs Cylinder.

It Doesn't Have to Be Circular

Usually when we say Cylinder we mean a Circular Cylinder, but you can also have Elliptical Cylinders, like this one:

And we can have stranger cylinders!

So long as the cross-section is curved and is the same from one end to the other, then it is a cylinder. But the area and volume calculations will be different than shown above.

More Cylinders

And what we can't we can"

Kindergarten Math

Kids love online flash games! They're a great way for students to brush up on their math vocabulary. Math games for kids can help make learning math fun with games, flash cards, worksheets, and activities. Math is so much easier when there are cool games to play for online learning. Children can start with flash cards and work up. Teaching math has never been easier! After studying addition facts, students can work on subtraction, multiplication, division, and other advanced facts as well. Math teachers can incorporate online flash games into their elementary math curricula. Elementary schools and middle schools are incorporating fun online games into their regular curricula as playing games, learning songs and watching educational videos online provide the results teachers want for their students. Songs and music can make learning even more fun! Even high school students love flash games, whether they're learning science, social studies, spelling, vocabulary, art, music, or language arts. Students of all ages-and even students learning ESL (English as a Second Language)-can benefit! Online lessons can help students improve their grades and do better in school. And best of all, kids are having fun while learning!
