Petar's curiosity was piqued, and he stepped into the circle. Suddenly, he found himself transported to a fantastical realm where circles and circumferences came to life.

"The Kruznica, our protective border, has been disrupted by mischievous Zadaci (tasks)," Krug said. "These Zadaci have been scattered throughout the kingdom, causing chaos and disorder. We need your help, Petar, to solve them and restore balance to our land."

In a small village, there lived a young boy named Petar who was studying mathematics in the 4th grade. One day, while walking home from school, he stumbled upon a mysterious circle drawn on the ground with chalk. As he approached the circle, he heard a gentle voice whispering his name.

In this realm, he met a friendly circle named Krug who introduced himself as the ruler of the land. Krug explained that his kingdom was filled with various shapes, but his people, the circles, were facing a problem.

The kingdom erupted in joy. Krug thanked Petar for his help and presented him with a special award: a golden compass with a circle and a circumference etched onto it. Petar's curiosity was piqued, and he stepped into the circle

"Petar, Petar! Come and explore the world of Krug (Circle) and Kruznica (Circumference)!"

The next task was: "If a circle has a diameter of 10 cm, what is its area?" Petar thought again and wrote: "A = π × (d/2)² = 3.14 × (10/2)² = 78.5 cm²." "These Zadaci have been scattered throughout the kingdom,

Finally, Petar solved the last Zadaci: "A circle has a circumference of 31.4 cm. What is its radius?" With a flourish, Petar wrote: "C = 2 × π × r => r = C / (2 × π) = 31.4 / (2 × 3.14) = 5 cm."
