Whakaoti i te r=sqrt{A/3}

$$r = \sqrt { \frac { A } { 3 } }$$

Whakaoti mō A

$$A=3r^{2}$$

$$r\geq 0$$

Ngā Upane mō te Whakaoti Whārite Pūtake

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

$$\sqrt{\frac{A}{3}}=r$$

Pūruatia ngā taha e rua o te whārite.

$$\frac{1}{3}A=r^{2}$$

Me whakarea ngā taha e rua ki te 3.

$$\frac{\frac{1}{3}A}{\frac{1}{3}}=\frac{r^{2}}{\frac{1}{3}}$$

Mā te whakawehe ki te \frac{1}{3} ka wetekia te whakareanga ki te \frac{1}{3}.

$$A=\frac{r^{2}}{\frac{1}{3}}$$

Whakawehe r^{2} ki te \frac{1}{3} mā te whakarea r^{2} ki te tau huripoki o \frac{1}{3}.

$$A=3r^{2}$$

Whakaoti mō A (complex solution)

$$A=3r^{2}$$

$$arg(r)<\pi \text{ or }r=0$$

Whakaoti mō r (complex solution)

$$r=\frac{\sqrt{3A}}{3}$$

Whakaoti mō r

$$r=\frac{\sqrt{3A}}{3}$$

$$A\geq 0$$
