This collection of problems on the circle ( krug ) and circumference ( kružnica ) is a solid resource for 4th graders mastering basic geometry concepts. It offers a good range of exercises—from identifying radius, diameter, and center points, to drawing circles with a compass and calculating simple perimeters (using π ≈ 3.14).

The first task read: "Calculate the circumference of a circle with a radius of 4 cm." Petar thought for a moment and then wrote down the answer using his magical pencil: "C = 2 × π × r = 2 × 3.14 × 4 = 25.12 cm." and center points
