Write a program that calculates the volume and surface area of a sphere.

Q. Write a program that calculates the volume and surface area of a sphere. The program must first ask the user to key in a radius value, r, before it performs the calculations. The program should display the result of the calculations. Save the program as "sphere.py".

 

Use the following formulae:

 

Surface area, S = 4 π r²

Volume, V = 4 / 3(π r³)

π = 3.142

 

Answer =

 

First make a module name with "sphere.py". Then write the program.

 

r = float (input ("Enter the Radius of sphere :- "))
print ("Surface Area :- ", 4 * 3.142 * r ** 2)
print ("Volume :- ", 4 / 3 * (3.142 * r ** 3))
