This is an example of how to find the height of a cylinder given the volume of the cylinder and the area of the base (circle):
What is the height of the cylinder?
Volume = Area of the base x height.........from here on out I will call "Area of the base" simply "area"
To figure this out,you have to get height by itself on the right side of the equal sign because height is what you are trying to find. To get height by itself, you have to take Area divided by itself and what ever you do to one side of the equal sign, you've got to do to the other. Then you take volume divided by area.
If you take 150 divided by 48 it equals 37.5. The height of the cylinder is 37.5 cm2.
To find the volume of a cylinder you have to use the formula:
Remember that there is a difference between the diameter and radius. The diameter is the length across the circle. The radius is from the middle of the circle to any point on the outside.
Also remember that radius squared is radius times radius, NOT radius times 2!

Hi I'm Kaitlin from Sargent Park in grade 8. I loved how u explained every thing and that you posted up your own pictures. Great job!
ReplyDeleteWhew! THAT was hard work.
ReplyDeleteHi there, I'm Harvey from Sargent Park as well. Wow, our math teacher never told us about volume and getting the height of a cylinder before. Thanks for the info.
