Volume of cones quick check

To calculate the volume of a cone, you can use the following formula:

Volume (V) = (1/3) * π * r² * h

where r is the radius of the base of the cone, h is the height of the cone, and π (pi) is approximately equal to 3.14159.

Let's do a quick check. If you have a cone with a radius (r) of 3 units and a height (h) of 4 units, the volume (V) would be:

V = (1/3) * π * 3² * 4
V = (1/3) * π * 9 * 4
V = (1/3) * π * 36
V = 12 * π
V ≈ 12 * 3.14159
V ≈ 37.6991 cubic units

So the volume of the cone with a radius of 3 units and height of 4 units would be approximately 37.6991 cubic units.
