Javob va yechimni ko‘rish
Javob: 12cm
Aylananing uzunligi (perimetri) formulasi $C=2\pi r$ yoki $C=\pi d$ ga teng, bu yerda $r$ radius, $d$ diametr. Bizga $C=12\pi\text{ cm}$ berilgan, shuning uchun formulaga $12\pi=\pi d$ yozamiz. Ikkala tomondan $\pi$ ni bo‘lsak, $12=d$ bo‘ladi. Demak, aylananing diametri $12\text{ cm}$ ga teng. To‘g‘ri javob: **D**.
