Find out how to derive the volumes of cones formula from almost absolute scratch. *If you'd really like to understand the deep concept of finding volumes, please watch the video below before you start watching the video above: https://www.youtube.com/watch?v=0X18YMac6bM *If you'd like to understand how I came up with a solution for finding volumes, please watch my videos on finding areas underneath curves below: https://www.youtube.com/watch?v=K4wW4zsFxq4 ... https://www.youtube.com/watch?v=0NUG_s1FxIg

In this video I demonstrate why, when x≡a(modm) and y≡b(modm) this means that xy≡(ab)(modm). The proof found in this video is related to the work in Further Pure Mathematics 2, Pearson, Page 12 and How To Think About Abstract Algebra, Lara Alcock, Page 44.
