Python Math: Calculate surface volume and area of a sphere

Python Math: Exercise-6 with Solution

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

Python: Volume of a sphere

The  area of a sphere is A = 4*π*r2

Python: Area of a sphere

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

Merging strings:

You can use join method to combine strings. Very useful indeed.

lst="Asia, Europe, Africa, Australia"
str=",".join(lst)
print(str)

Output:

A,s,i,a,,, ,E,u,r,o,p,e,,, ,A,f,r,i,c,a,,, ,A,u,s,t,r,a,l,i,a
