What is the radius of a circle with a diameter of 14'?

The radius of a circle is defined as half of its diameter. Given a diameter of 14 feet, to find the radius, you divide the diameter by 2.

So, 14 feet ÷ 2 = 7 feet.

This calculation shows that the radius of the circle is 7 feet, making it the correct choice. Understanding this relationship between diameter and radius is fundamental to geometry and is commonly applied in various fields, including carpentry and millwork, where precise measurements are critical for cutting and fitting materials.
