    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))
