Introduction

The circumference of a circle is a fundamental concept in mathematics, and it is essential to understand the formula and its equivalent equations. The formula for the circumference of a circle is given by C=2πrC = 2 \pi r, where CC is the circumference and rr is the radius of the circle. In this article, we will explore the equivalent equation solved for rr and discuss the correct answer among the given options.

Understanding the Formula

The formula C=2πrC = 2 \pi r is a fundamental concept in mathematics, and it is used to calculate the circumference of a circle. The circumference of a circle is the distance around the circle, and it is measured in units such as meters, feet, or inches. The radius of a circle is the distance from the center of the circle to the edge, and it is also measured in units such as meters, feet, or inches.

Solving for rr

To solve for rr, we need to isolate the variable rr on one side of the equation. We can do this by dividing both sides of the equation by 2π2 \pi. This will give us the equivalent equation solved for rr.

Equivalent Equation Solved for rr

To find the equivalent equation solved for rr, we need to divide both sides of the equation C=2πrC = 2 \pi r by 2π2 \pi. This will give us:

r=C2πr = \frac{C}{2 \pi}

Analyzing the Options

Now that we have found the equivalent equation solved for rr, let's analyze the options given:

A. r=Cπr = \frac{C}{\pi}

B. r=C(2π)r = C(2 \pi)

C. r=C2πr = \frac{C}{2 \pi}

D. r=2Cr = \frac{2}{C}

Correct Answer

Based on our analysis, the correct answer is:

C. r=C2πr = \frac{C}{2 \pi}

This is the equivalent equation solved for rr, and it is derived from the original formula C=2πrC = 2 \pi r by dividing both sides by 2π2 \pi.

Conclusion

In conclusion, the circumference of a circle can be found using the formula C=2πrC = 2 \pi r. The equivalent equation solved for rr is r=C2πr = \frac{C}{2 \pi}. This equation is derived from the original formula by dividing both sides by 2π2 \pi. We analyzed the options given and found that option C is the correct answer.
