الدائرة: الدائرة ومحيطها - حل مسائل 2

The video tutorial explains how to find the diameter and radius of a circle. It starts by determining the diameter of a circle when the length of a segment TU is given as 14 feet. The diameter is identified as 14 feet, and the radius is calculated as half of the diameter, resulting in 7 feet. The tutorial then shifts to another example where the length of segment QT is 11 meters, representing the radius. It confirms that the radius is 11 meters and explains that the length from the center to any point on the circle is constant, thus the length QU is also 11 meters.
