Whakaoti i te r=18cm.piapprox22/7

$$r = 18 cm . \pi \approx \frac { 22 } { 7 }$$

Whakaoti mō c (complex solution)

$$\left\{\begin{matrix}c=\frac{r}{18m}\text{, }&m\neq 0\\c\in \mathrm{C}\text{, }&r=0\text{ and }m=0\end{matrix}\right.$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.

$$18cm=r$$

He hanga arowhānui tō te whārite.

$$18mc=r$$

Whakawehea ngā taha e rua ki te 18m.

$$\frac{18mc}{18m}=\frac{r}{18m}$$

Mā te whakawehe ki te 18m ka wetekia te whakareanga ki te 18m.

$$c=\frac{r}{18m}$$

Whakaoti mō m (complex solution)

$$\left\{\begin{matrix}m=\frac{r}{18c}\text{, }&c\neq 0\\m\in \mathrm{C}\text{, }&r=0\text{ and }c=0\end{matrix}\right.$$

$$18cm=r$$

Whakawehea ngā taha e rua ki te 18c.

$$\frac{18cm}{18c}=\frac{r}{18c}$$

Mā te whakawehe ki te 18c ka wetekia te whakareanga ki te 18c.
