Sphere geometry parameter online calculator

App description

A semicircle revolves around a straight line of diameter to form a spatial geometry called a sphere. The radius of a semicircle is the radius of the sphere. A sphere is a solid figure with and only one continuous surface, which is called a sphere.

The forward projection of a sphere on any plane is a circle of equal size, and the diameter of the projected circle is equal to the diameter of the sphere.

The calculation formula of the surface area and volume of the sphere:

Sphere volume \(V=4/3πR^3\)

Sphere surface area \(S=4πR^2\)

Usage example

Input data:

Input: 4

This number is: radius

When radius = 4

Then this sphere:

Diameter = 8

Perimeter = 25.133

Area = 201.06

Volume = 268.08
