What is the term for a 3D shape that looks like a ball?
Show answer
Sphere
A sphere is a perfectly symmetrical set of points in 3D space that are all equidistant from a single center point. Unlike a circle, which is 2D, a sphere has volume and surface area, and it is the shape that naturally occurs when surface tension pulls a liquid into its most compact form.
