Whakaoti mō C
C=\pi d
Tohaina
Kua tāruatia ki te papatopenga
\pi d=C
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
\frac{\pi d}{\pi }=\frac{C}{\pi }
Whakawehea ngā taha e rua ki te \pi .
d=\frac{C}{\pi }
Mā te whakawehe ki te \pi ka wetekia te whakareanga ki te \pi .
