Apr 04, 2016 · This is the third and final post on the volume of a sphere. The other two can be accessed by the following links, "Coordinates in 3-Space" and "The Volume of a Sphere with Calculus" As the title suggests, this will be a derivation without the use of Calculus. Sphere, Volume Demonstration of the volume of a sphere based on a modification of Archimedes proof. Archimedes realized that the volume of a sphere equals the volume of a cylinder (of the same height and radius) minus the volume of a cone (of the same height and radius).

Pupils learn to calculate the volume and surface area of spheres using the relevant formulae. There is a selection of harder questions to challenge the more able on the sheet. In the powerpoint is a link to a demonstration of the formula (not involving calculus as students studying this topic most likely will not have encountered this yet!). Zu Geng, born about 450, was a chinese mathematician who used what is now know as the Principle of Liu Hui and Zu Geng to calculate the volume of a sphere. Liu-Zu theory is equivalent to Cavalieri's Principle. Then, chinese mathematicians had used this principle for more than one millennium before Cavalieri. In the 3rd century BC, Archimedes, using a method resembling Cavalieri's principle, was able to find the volume of a sphere given the volumes of a cone and cylinder in his work The Method of Mechanical Theorems. In the 5th century AD, Zu Chongzhi and his son Zu Gengzhi established a similar method to find a sphere's volume. Feb 12, 2005 · i.e. you approximate a sphere's volume by that of a family of pyramids, each with vertex at the origin, nd base rectangles on the surface of the sphere. each has volume equal to (1/3) base area times height, whicha s you take more pyramids, approacjes (1/3) (area of sphere) (radius of sphere).

Volume formula derivations Sphere. The volume of a sphere is the integral of an infinite number of infinitesimally small circular disks of thickness dx. The calculation for the volume of a sphere with center 0 and radius r is as follows. The surface area of the circular disk is . Now, to find the volume of a sphere-- and we've proved this, or you will see a proof for this later when you learn calculus. But the formula for the volume of a sphere is volume is equal to 4/3 pi r cubed, where r is the radius of the sphere. So they've given us the diameter. And just like for circles, the radius of the sphere is half of the ...

In geometry, a sphere packing is an arrangement of non-overlapping spheres within a containing space. The spheres considered are usually all of identical size, and the space is usually three-dimensional Euclidean space. However, sphere packing problems can be generalised to consider unequal spheres, spaces of other dimensions or to non-Euclidean spaces such as hyperbolic space. A typical sphere packing problem is to find an arrangement in which the spheres fill as much of the space as possible.
