Question
Write a function to calculate and return the area of a circle by using the radius of the circle given as a parameter.Notes: Round up the area to 2 decimal places. You can use the round() function. Use pi as 3.14159. You need not take input in this problem, you need to only implement the function provided.
Solution
Here is a Python function that calculates the area of a circle given its radius:
def calculate_area(radius):
pi = 3.14159
area = pi * (radius**2)
return round(area, 2)
This function works as follows:
- It first defines the value of pi as 3.14159.
- It then calculates the area of the circle using the formula
pi * radius^2. - The
round()function is used to round the calculated area to 2 decimal places. - Finally, the function returns the calculated and rounded area.
