## Python Programs to Calculate Area of Circle

### 1. By Anon

Made by C Anon. Program to calculate area of circle. Source

```enter radius:10
Area of circle is calculated below:
314.0```
``````a=int(input('enter radius:'))
print(a)
print('Area of circle is calculated below:')
print(3.14*(a**2))
print('this is a program which can find area of circle of given radius')``````

Made by Julius Abucejo. Simple Circle Area Calculator made using Python. Source

```Enter the radius of the circle: 11
The area of the circle is:
380.132711084365
```
``````#import math module
from math import*
a= float (input("Enter the radius of the circle: \n"))
area=pi*(a**2)
print("The area of the circle is: ")
print (area)``````

### 3. By Joelsays

```input the radius value 12
the area of the circle is
904.0```
``````r=float(input("input the radius value "))
#i used float above in case user input is in decimal
pi=float(3.142)
c=int(2*pi*(r**2))
print ("the area of the circle is")
print (float(c)) ``````
