This math topic focuses on calculating the area of a circle with an inscribed square. Problems are given where the area of the square is known, and students are asked to determine the area of the circle. Seven questions are presented, each with a different square area (4, 9, 16, 25, 36, 49, 64). Each question has multiple-choice answers represented in various mathematical expressions and forms involving square roots, powers, and π (pi). The knowledge and skills practiced here include understanding geometric relationships and applying algebraic formulas to find areas.
