Topic: Python Find Area of Circle using User Defined Function
The area of a circle is given by the formula:
area = PI x R2
where PI is the popular math constant = 3.14159 and R is the radius of the circle.
We will use the math module in this Python program. Import math module and use math.pi. To calculate R squared we will use the power operator ** with 2 as power.
We will use the Python expression for area of circle formula:
area= math.p * radius**2
Output Python Find Area of Ciircle
Enter value for base of triangle:7.3 The Area of circle is : 167.4155
