Zadana je kružnica \omega_0 u koju su upisane tri sukladne kružnice tako da su sve četiri kružnice međusobno tangentne. U dio ravnine između tri manje kružnice upisana je nova kružnica \omega_1 koja izvana dodiruje svaku od tih triju kružnica. Taj postupak upisivanja kružnica se nastavlja u beskonačnost. Ako je radijus kružnice \omega_0 jednak 28, koliki je radijus kružnice \omega_{39}? Rješenje upišite u znanstvenom zapisu s dvije decimale, sve bez razmaka (npr. 2.80*10^(-39)).
A circle \omega_0 is given, inside of which three congruent circles are inscribed, such that all four circles are mutually tangent. In the region of the plane between the three smaller circles, a new circle \omega_1 is inscribed, touching each of the three circles externally. This process of inscribing circles continues infinitely. If the radius of circle \omega_0 is 28, what is the radius of circle \omega_{39}? Write your answer in scientific notation with two decimal places, with no spaces (e.g. 2.80*10^(-39)).
