Question

Write a Python program which accepts the radus of a circle from ihe user and compute
the area.​

Answer 1

Answer:

Write a Python program which accepts the radius of a circle from the user and compute the area.

Python: Area of a Circle

In geometry, the area enclosed by a circle of radius r is πr2. Here the Greek letter π represents a constant, approximately equal to 3.14159, which is equal to the ratio of the circumference of any circle to its diameter.

Python: Area of a circle

Sample Solution:-

Python Code:

from math import pi

r = float(input ("Input the radius of the circle : "))

print ("The area of the circle with radius " + str(r) + " is: " + str(pi * r**2))

Copy

Sample Output:

Input the radius of the circle : 1.1                                                                          

The area of the circle with radius 1.1 is: 3.8013271108436504  

Flowchart:

Flowchart: Input the radius of a circle  and compute the area.

Answer 2

r = float(input("Enter the radius of the circle: "))

print("Area of the circle =", 3.14 * (r * r))
