Answer
from math import pi
r=float(input("Enter the radius: "))
print("The circumference is:", 2*pi*r)
print("The area is:", pi*r*r)
Work Step by Step
Circumference of circle is $2\times \pi\times r$
Area of circle is $\pi\times r^{2}$
from math import pi
r=float(input("Enter the radius: "))
print("The circumference is:", 2*pi*r)
print("The area is:", pi*r*r)
