This topic focuses on determining the full area of a circle from the given area of a sector. Skills practiced include calculating the area of circular sectors, understanding fractions of whole circles, and applying the value of pi (π) in arithmetical operations, all within the context of basic geometry involving circles. Each problem provides a fraction of a circle's area, and students must calculate the area of the whole circle based on the given sector's area. This offers valuable practice in applying geometric and proportional reasoning skills.
