Introduction

In this problem, we are given a square with a side length of 11 units. We need to find the area of a circle whose circumference is equal to the perimeter of the square. To solve this problem, we will first calculate the perimeter of the square, then use it to find the radius of the circle, and finally calculate the area of the circle.

Calculating the Perimeter of the Square

The perimeter of a square is given by the formula P = 4s, where s is the length of one side of the square. In this case, the side length of the square is 11 units.

# Calculating the perimeter of the square
s = 11  # side length of the square
P = 4 * s  # perimeter of the square
print("The perimeter of the square is:", P)

Calculating the Circumference of the Circle

The circumference of a circle is given by the formula C = 2πr, where r is the radius of the circle. We are given that the circumference of the circle is equal to the perimeter of the square, so we can set up the equation 2πr = P.

Finding the Radius of the Circle

We can now solve for the radius of the circle by dividing both sides of the equation by 2π.

# Finding the radius of the circle
import math
π = 3.14  # value of pi
r = P / (2 * π)  # radius of the circle
print("The radius of the circle is:", r)

Calculating the Area of the Circle

The area of a circle is given by the formula A = πr^2. We can now calculate the area of the circle using the value of the radius we found earlier.

# Calculating the area of the circle
A = π * (r ** 2)  # area of the circle
print("The area of the circle is:", round(A, 2))

Conclusion

In this problem, we found the area of a circle whose circumference is equal to the perimeter of a square with a side length of 11 units. We first calculated the perimeter of the square, then used it to find the radius of the circle, and finally calculated the area of the circle.

Final Answer

The final answer is: approximately 201.06 square units.

Discussion

This problem requires a good understanding of the formulas for the perimeter and area of a square and the circumference and area of a circle. It also requires the ability to set up and solve equations to find the radius of the circle.
