Question

Write a program to enter radius of circle and calculate area and circumference in python

Answer 1

The following codes must be typed in script mode, saved and them executed.

CODE 1:

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

area = 3.14*r**2

circ = 2*3.14*r

print("The area of  the circle is", area)

print("The circumference of the circle is:", circ)

OUTPUT:

$\tt Enter\ the\ radius\ of\ the\ circle:$ 5

$\tt The\ area\ of\ the\ circle\ is\ 78.5\\The\ circumference\ of\ the\ circle\ is\ 31.4$

CODE 2:

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

print("The area of  the circle is", 3.14*r**2)

print("The circumference of the circle is:", 2*3.14*r)

OUTPUT:

$\tt Enter\ the\ radius\ of\ the\ circle:$ 5

$\tt The\ area\ of\ the\ circle\ is\ 78.5\\The\ circumference\ of\ the\ circle\ is\ 31.4$
