Area of a Part Circle - Part Area and Fraction to Full Area (Pi Value)

This math topic focuses on understanding and calculating the area of a part circle and extending this information to find the full area of the circle using the value of π (Pi). Specifically, learners are given the area of a sector (either explicitly or through a fraction like 1/2 of the circle) and are required to determine the total area of the circle. These problems enhance skills in handling spatial relationships and fractions tied to areas within the broader scope of geometry, specifically focusing on circles and their parts. The problems help solidify the fundamental principles of circle geometry by applying the relationship between the part and the whole through practical examples.
