Answer
The circumference is 87.92 inches.
Solution
The formula for the circumference of a circle is C = 2πr. With a radius (r) of 14 inches and π approximated as 3.14, you can calculate:
C = 2 × 3.14 × 14
C = 87.92 inches
Rounded to the nearest hundredth, the circumference is 87.92 inches.

Simplify this solution Beyond the Answer
To find the circumference of a circle, you can use the formula \( C = 2\pi r \). With a radius of 14 inches, the calculation would be \( C = 2 \times 3.14 \times 14 \). This gives you a circumference of approximately 87.92 inches when rounded to the nearest hundredth. The concept of circumference dates back to ancient civilizations! The Egyptians and Babylonians both had methods to approximate \(\pi\) long before it was formally defined. Their empirical techniques laid the groundwork for modern mathematics, making the circle one of the most studied shapes throughout history!
