What is the Circumference of a Circle with a Radius of 28 Feet?

Understanding the Concept of Circumference

The circumference of a circle is a fundamental concept in mathematics that refers to the distance around the circle. It is an essential parameter in various mathematical and real-world applications, such as geometry, trigonometry, and engineering. In this article, we will explore the concept of circumference and calculate the circumference of a circle with a radius of 28 feet.

What is Circumference?

Circumference is the distance around a circle, which is also known as the perimeter of the circle. It is a measure of the distance that a person would travel if they walked around the circle. The circumference of a circle is typically denoted by the symbol C and is calculated using the formula:

C = 2πr

where C is the circumference, π (pi) is a mathematical constant approximately equal to 3.14, and r is the radius of the circle.

Using $\frac{22}{7}$ for $\pi$

In this problem, we are given the value of $\pi$ as $\frac{22}{7}$. This is a common approximation of $\pi$ used in mathematics and is sufficient for most calculations.

Calculating the Circumference

Now that we have the formula for calculating the circumference and the value of $\pi$, we can calculate the circumference of the circle with a radius of 28 feet.

C = 2πr C = 2 × $\frac{22}{7}$ × 28 C = 2 × 22 × 4 C = 176

Conclusion

Therefore, the circumference of a circle with a radius of 28 feet is 176 feet.
