learn how to find the diameter of a circle given the area

The video tutorial explains how to find the diameter of a circle given its area. It begins with a review of the circle's characteristics, including the relationship between the radius and diameter. The instructor guides students through solving for the radius using the area formula, emphasizing the importance of using the exact value of π. Finally, the diameter is calculated by doubling the radius, and students are encouraged to verify their understanding.
