Matematika 4 - Razred Krug I Kruznica Zadaci

Petar bravely accepted the challenge. Krug handed him a magical pencil and a worksheet containing various tasks related to circles and circumferences.

Krug smiled, impressed with Petar's work. "Well done, Petar! You've solved the first Zadaci. Move on to the next one."

"Petar, Petar! Come and explore the world of Krug (Circle) and Kruznica (Circumference)!" Matematika 4 Razred Krug I Kruznica Zadaci

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.

I hope you enjoyed this story!

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."

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." Petar bravely accepted the challenge

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.
