Aylanish figuralari

Yechilishi:

Masala shartiga ko`ra S_yon = 2 · S_asoc ,

\
S_ABC = Q. Ma`lumki S_yon = πrℓ= π · AO · AC,

S_asoc = πr² = π · AO², S_ABC = AO · OC.

formulalar yordamida hisoblanadi. Yuqo-

ridagilarni e`tiborga olsak, ℓ= 2r ya`ni

AC = 2AO, shu bilan birga

Q = AO · = AO² · .

ekanligini topish mumkin. Bundan AO =

Konus hajmi V = π · · · = .
