# Python: Calculate volume of sphere

## Python Basic: Exercise-15 with Solution

Write a Python program to get the volume of a sphere with radius six.

**Python: Volume of a Sphere**

A sphere is a three-dimensional solid with no face, no edge, no base and no vertex. It is a round body with all points on its surface equidistant from the center. The volume of a sphere is measured in cubic units.

The volume of the sphere is : V = 4/3 × π × r3 = π × d3/6.

**Sample Solution:**

**Python Code:**

```
# Define the value of pi
pi = 3.1415926535897931
# Define the radius of the sphere
r = 6.0
# Calculate the volume of the sphere using the formula
V = 4.0/3.0 * pi * r**3
# Print the calculated volume of the sphere
print('The volume of the sphere is: ', V)
```

Sample Output:

The volume of the sphere is: 904.7786842338603

**Explanation:**

The said code assigns the value of pi as 3.1415926535897931 to the variable "pi" and 6.0 to the variable "r". The code uses the formula V = 4/3 * pi * r^3 to calculate the volume of a sphere. Volume of the sphere is stored in the variable "V".

It then prints the message "The volume of the sphere is:" followed by the volume of the sphere using print statement.

In this case, the code will output "The volume of the sphere is: 904.7786842338603".

**Flowchart:**

**Python Code Editor:**

**Previous:** Write a Python program to calculate number of days between two dates.

**Next:** Write a Python program to get the difference between a given number and 17, if the number is greater than 17 return double the absolute difference.
