A circle is inscribed in a square. If the area of the square is 36 square units, what is the area of the circle?
✓ Correct Answer: Option B
If the square's area is 36, its side length is √36 = 6 units. The diameter of the inscribed circle is equal to the square's side length, so d=6. The radius is r=3. Area of circle = πr² = π(3)² = 9π.
