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."
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
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." The next task was: "If a circle has
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. The circles and circumferences started to align properly,
Krug smiled, impressed with Petar's work. "Well done, Petar! You've solved the first Zadaci. Move on to the next one."
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.
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."
