WebA sphere can be formed by revolving a semicircle about is diameter edge. The area of the semicircle is 1 2πr2. The centroid of the semicircle can be found by intersecting two lines that both divide the area of the semicircle into two equal parts. WebSphere is a level set of the function F ( x, y, z) = x 2 + y 2 + z 2. For example, F ( x, y, z) = 1 corresponds to the sphere of the radius 1.
