An **online sphere calculator** lets you to find the volume and curved surface area of any spherical object, given the radius of the object. In a sphere, distance from the center is the radius of the ball (r). Calculate the volume and curved surface area(CSA) of spherical ball in just a single click.

**Sphere:**

It is a three-dimensional ball like structure with a bit of flat surface on top and bottom. It is a closed surface such that every point on the surface is equidistant from the center. Mathematically, a sphere is defined as the set of points that are all at the same distance r from a given point. It is identical to a circle except for the top and bottom flat surfaces. The Planet, Ball, Marble, Orange, Bubble, Bauble are examples of spherical objects.

**Volume of a Sphere:**

Volume of any 3-dimensional solid is the amount of space it occupies. Volume of a sphere refers to the number of cubic units that fully occupies(fills) a sphere. It is three-fourth of the product of the cube of its radius and the constant π.

**Curved Surface Area (CSA) of Sphere:**

The curved surface area of sphere, also known as Surface Area or the Lateral Area is the area of a disk enclosed by a sphere. The curved surface area of a sphere is four times the product of the square of its radius and the constant π.

Make use of this sphere calculator to practice and compute the volume and curved surface area of the sphere with ease.
