## anonymous 4 years ago How do you find the volume, I forgot?

1. anonymous

of?

2. anonymous

Volume varies from object to object, in geometry you memorize a lot of formulas for different volumes, and in Calculus you learn how to implement those memorized formulas in order to find more complex volumes.

another bored question?:P

A cylinder

5. anonymous

pi r^2 * h

6. anonymous

Generally we use integration. For the cylinder $$V = \pi r^2 h$$

7. anonymous

Oh, okay thanks guys!

8. anonymous

to remember cylender just remember that you can think of it as the area of a circle. ANd think of a bunch of rings stacked up on top of eachother then see how high the stack is and you can therefore say pi r^2 h :)

9. anonymous

Okay! :)

stick it in some water and see how much water is displaced... :)

11. anonymous

Ha, okay Dpalnc!

12. anonymous

she'd have to build the cylendar :D
