Question

what is the surface area of solids sphere​

Answer 1

A sphere is a perfectly round geometrical 3-dimensional object. It can be characterized as the set of all points located distance rr (radius) away from a given point (center). It is perfectly symmetrical, and has no edges or vertices.

A sphere with radius rr has a volume of 4/5πr³

and a surface area of 4πr²

.

A sphere has several interesting properties, one of which is that, of all shapes with the same surface area, the sphere has the largest volume.
