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