Question

Python

Write definitions for these functions:
sphereArea(radius) returns the surface area of a sphere having the given radius.
sphere Volume (radius). Returns the volume of a sphere having the given radius.

from math import pi

def sphere_area(r):
    """Area of a sphere with radius r."""

    *** YOUR CODE HERE ***

def sphere_volume(r):
    """Volume of a sphere with radius r."""

    *** YOUR CODE HERE ***

Answer 1

The answer to the question is given below.


The python code is given below.

#import pi from math package
from math import pi

#defination for area of sphere
def sphere_area(r):
return (4*pi*r*r)

#defination for volume of sphere
def sphere_volume(r):
return((4/3)*pi*r*r*r)

#Getting the radius from user
r=float(input("Enter the radius of spehere: "))
#calling the both function and getting the return value in variable area and spehere
area=sphere_area(r)
volume=sphere_volume(r)

#Displaying the area and volume
print("Area of the sphere is : ",area)
print("Volume of the sphere is : ",volume)
