Area of a Circle - Diameter to Equation (Level 1)

This math topic focuses on calculating the area of a circle using the given diameter. It is designed to help students form equations for the circle's area based on its diameter, transitioning from direct measurements to algebraic expressions involving pi. The problems are structured to enhance understanding of circle geometry, particularly applying the formula for the area of a circle (πr²) through various scenarios and diameters, requiring students to calculate radii and substitute values correctly into the formula.
