The volume would be pi(r^2)(h). That means 3.14 multiplied by the radius squared(radius*radius) multiplied by the height
3.14(5^2)(18) = 3.14(25)(18) = 3.14(450) = 1413
The volume of the can is 1413 cubic centimeters

Firstly, the formula for the area of a circle is pi mutiplied by the radius , squared.
Next, the volume of an object is calculated by multiplying the area of the base by the height.
With that information, we can get on with the problem.
Sine the radius is 5, you would first enter pi into your SCIENTIFIC calculator, then 5. Press the equal key and then hit the squaring button (X with a small 2)
When you get the area of the circle, which is the area of your base you can multiply it by 18 to find the volume of the cylinder (can).
For best accuracy, use your result from the previous step and follow the decimal accordingly.
Once you have done that you are finished!!! :^)

It's the area of the bottom (pi times radius squared,) times the height.
