Salut!
Răspuns: [tex]22\pi \: cm[/tex] ✅
[tex] \it{ \red{lungime \: cerc \: = 2 \times \pi \times r}}[/tex]
[tex] \red{ \it{diametrul = 2 \times r}}[/tex]
[tex] \red{ \it{r = raza}}[/tex]
Diametrul = 22 cm
R = 22 : 2
R = 11 cm
[tex] \bf{lungime \: cerc = 2 \times \pi \times 11 = \boxed{ 22\pi \: cm}}[/tex] ✔
