Hi, I'm Rachel, and today we're going to be going over how to find the volume of a cylinder filled with water. The important things you need to know about the cylinder that's filled with water are the height and the radius of the circle. If you know the diameter of the circle, that's okay too you can just divide it by 2 to find the radius. And of course you need to memorize the formula. The volume is just the area of the circle multiplied by the height of the cylinder. So let's say you have a circle with a diameter of 6 so it has a radius of 3 and it has a height of 10. Well you just plug in you know, the radius is 3 squared, the height is 10, multiply it all together, 3 squared is 9 times 10 is 90, you get 90 Pi and then you just have to remember to write units cubed. Whatever the units are make sure you write them cubed because that's how we always express volume in cubic units. I'm Rachel, and thanks for learning with me today.
