## What is Sphere?

A sphere is a three-dimensional geometric shape that is perfectly round in shape, similar to a ball or a globe. It is one of the most basic and symmetrical three-dimensional objects in geometry. A sphere is defined as the set of all points in space that are equidistant (at the same distance) from a central point called the center of the sphere. The distance from the center to any point on the surface of the sphere is called the radius.

## All Formulae Related to Sphere

Basic Dimensions:

• Diameter (D): D = 2r (where r is the radius)
• Circumference (C): C = 2πr
• Surface Area (SA): SA = 4πr²

2. Volume:

• Volume (V): V = (4/3)πr³

3. Other Calculations:

• Area of a hemisphere: SAhemisphere = (1/2) * SAsphere
• Volume of a hemisphere: Vhemisphere = (1/2) * Vsphere
• Area of a great circle: Acircle = πr² (formed by intersecting the sphere with a plane passing through its center)
• Radius of a sphere given its volume: r = ³√(3V / (4π))
