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."
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.
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. Matematika 4 Razred Krug I Kruznica Zadaci
As Petar returned to his village, he realized that he had learned something valuable: mathematics was not just about numbers and formulas, but about solving problems and helping others.
I hope you enjoyed this story!
Petar bravely accepted the challenge. Krug handed him a magical pencil and a worksheet containing various tasks related to circles and circumferences.
As Petar continued to solve the Zadaci, the kingdom began to transform. The circles and circumferences started to align properly, and the land became more harmonious. Finally, Petar solved the last Zadaci: "A circle
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."
