The shape of the top and bottom are perfect circles whose centers are directly aligned. Using Cartesian coordinates and putting the origin at the centre, we derive the familiar equation (1.1) x2 +y2 +z2 = R2, where R is the radius; the sphere is the set of all points in R3 whose . a is the radius of one end. Suppose, you have to covert the equation 5r=sin (). An ellipse is defined as the locus of all points in the plane for which the sum of the distances r1 and r2 to two fixed points F1 and F2 (called the foci) separated by a distance 2c, is a given constant 2a. For the parabola, the standard form has the focus on the x-axis at the point (a, 0) and the directrix is the line with equation x = a. Taking those points on the sphere where z equals v, the equation becomes x2 + y2 + v2 = R2 or x2 + y2 = R2 - v2 Notice that setting r so that r2 = R2 - v2 this equation becomes x2 + y2 = r2 which is the equation of a circle of radius r in the plane with z -coordinate v.
