The volume of a pyramid is 1/3 the volume of a prism.

The volume of a cone is 1/3 the volume of a cylinder

To find the volume of a cone, you would use

V=πr2h/3

You would use this formula because first you must find the area of the circular base, which is πr2. Then you would multiply the base by the height, and that would give you the volume of a cylinder. From there you divide by 3 to get the volume of the cone because A cone is a third of a cylinder.

Q2

alrabd1 — 2015-03-05 14:48:19 UTC

An oblique pyramid does not have the apex(the point where all the sides meet is not over the center of the base.The opposite would be a right pyramid.

Q2: How does the volume of a right pyramid compare to the volume of an oblique pyramid?

geospi1 — 2015-03-06 14:13:51 UTC

The area of a right pyramid is 1/3 b*h to find the area of an oblique pyramid you would use the formula 1/3 (area of base)(h)
