Area of a Circle Donut From Outer Radius and Area to Inner Radius (Closest Integer)

This math topic focuses on finding the inner radius of a donut shape given the outer radius and the total area of the donut. The topic is introduced as part of a beginner's unit on the geometry of circle areas, sectors, and donuts. Each question requires the student to calculate the inner radius using two provided pieces of information: the total area of the donut and the length of the outer radius. The answers are presented in a multiple-choice format, challenging the student to solve the problem and select the closest integer solution. This task strengthens skills in both geometry and algebraic manipulation.
