### What Is Sphere?

In geometry, a sphere is a solid, that is absolutely round in shape defined in three-dimensional space . Mathematically, a sphere is defined as the set of points that is at equal distances from a common point in three dimensional space. This constant distance is called radius of sphere and the common point is the center of sphere.

### What Are Calculation Option Available In Sphere?

Select Which value you are providing (Radius (r), Volume (V), Circumference (C), Surface area (A)) input value and click on Calculate.

In geometry, a sphere is a solid, that is absolutely round in shape defined in three-dimensional space (XYZ space). Mathematically, a sphere is defined as the set of points that is at equal distances from a common point in three dimensional space. This constant distance is called radius of sphere and the common point is the center of sphere. To Calculate all the properties of Sphere this calculator is helpfull . Using the following formula :-

**Volume of a Sphere :**
V = (4/3)pr^{3}

Where

V = Volume

r = radius

**Circumference of a Sphere :**
C = 2pr

Where

C = Circumference

r = radius

**Surface area of a Sphere:**
A = 4pr^{2}

Where

A = surface area

r = radius

### How to use Sphere Calculator?

Step by step procedure for Sphere Calculator is as follows.

**Step 1: **Select which value you will be providing? Dropdown list has (Radius (r), Volume (V), Circumference (C), Surface area (A)) options.

**Step 2: **Input appropriate value as per selected type in Step 1.

**Step 3: **Now click on "Calculate" button to get result.

You will get Radius (r), Volume (V), Circumference (C), Surface area (A) as per your value input.
