# (Python Example for Citizen Data Scientist & Business Analyst)

Write a Python program to calculate surface volume and area of a sphere.

Note: A sphere is a perfectly round geometrical object in three-dimensional space that is the surface of a completely round ball.

Python: Surface volume and area of a sphere

A sphere is a perfectly round geometrical object in three-dimensional space that is the surface of a completely round ball.

In three dimensions, the volume inside a sphere is derived to be V = 4/3*π*r3 where r is the radius of the sphere

The  area of a sphere is A = 4*π*r2

Sample Solution:

Python Code:

``````
pi=22/7
radian = float(input('Radius of sphere: '))

sur_area = 4 * pi * radian **2

volume = (4/3) * (pi * radian ** 3)

print("Surface Area is: ", sur_area)
print("Volume is: ", volume)
``````

Sample Output:

```Radius of sphere: .75
Surface Area is:  7.071428571428571
Volume is:  1.7678571428571428```
