Whakaoti i te 500=3.14*6.5^2*x/4

$$500 = 3.14 \times { 6.5 }^{ 2 } \times \frac{ x }{ 4 }$$

Whakaoti mō x

$$x = \frac{400000}{26533} = 15\frac{2005}{26533} \approx 15.075566276$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakareatia ngā taha e rua o te whārite ki te 4.

$$2000=3.14\times 6.5^{2}x$$

Tātaihia te 6.5 mā te pū o 2, kia riro ko 42.25.

$$2000=3.14\times 42.25x$$

Whakareatia te 3.14 ki te 42.25, ka 132.665.

$$2000=132.665x$$

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

$$132.665x=2000$$

Whakawehea ngā taha e rua ki te 132.665.

$$x=\frac{2000}{132.665}$$

Whakarohaina te \frac{2000}{132.665} mā te whakarea i te taurunga me te tauraro ki te 1000.

$$x=\frac{2000000}{132665}$$

Whakahekea te hautanga \frac{2000000}{132665} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.

$$x=\frac{400000}{26533}$$
