WebA sphere is a perfectly round 3-dimensional object. It is an object with the shape of a round ball. The distance from the center of a sphere to any point on its surface is called the … WebThe formula for the volume of a sphere is V = 4/3 π r³, where V = volume and r = radius. The radius of a sphere is half its diameter. So, to calculate the surface area of a sphere given the diameter of the sphere, you can first calculate the radius, then the volume.

For objects of large diameter (a planet even), measure the maximum angle subtended between accurate observation of the points furthest apart on the opposite sided of the sphere. Call that angle θ. Call the diameter d, (d=2r where r is the radius of the sphere). Call the distance from the observer to the centre of the sphere D; measure or ... duty of guest service agent
