Circles on the sphere are, like circles in the plane, made up of all points a certain distance from a fixed point on the sphere. The intersection of a sphere and a plane is a circle, a point, or empty. Great circles are the intersection of the sphere with a plane passing through the center of a sphere: others are called small circles. WebThe diameter of a sphere: The line passing through the center from one end to the other called the diameter of the sphere. The diameter of the sphere denoted as D. Diameter = 2 times radius of the sphere. D = 2 × r. Circumference of a sphere: Circumference of a sphere is the distance covered around the sphere. The unit of the circumference is ...
