WebRadius is the distance from the center of the circle to any point on its circumference, which means the line segment that connects the center of a circle to any point on its circumference is called the radius. Since there are infinite points on its circumference, this means that a circle has an infinite number of radii (plural form of radius). WebIn analytical geometry, if “r” is the radius, (x, y, z) is the locus of all points and (x0, y0, z0) is the center of a sphere, then the equation of a sphere is given by: (x -x0)2 + (y – y0)2 + (z-z0)2 = r2 Sphere Formulas The common formulas of the sphere are: Surface area Volume Surface Area of a Sphere bracey-online.com
