Ka whakawehea he tau ki te tahi, hua ai ko ia anō.

$$\sqrt{3}\times \frac{5\times 9\times 15\sqrt{3}\pi }{81}$$

Whakareatia te 5 ki te 9, ka 45.

$$\sqrt{3}\times \frac{45\times 15\sqrt{3}\pi }{81}$$

Whakareatia te 45 ki te 15, ka 675.

$$\sqrt{3}\times \frac{675\sqrt{3}\pi }{81}$$

Whakawehea te 675\sqrt{3}\pi ki te 81, kia riro ko \frac{25}{3}\sqrt{3}\pi .

$$\sqrt{3}\times \frac{25}{3}\sqrt{3}\pi$$

Whakareatia te \sqrt{3} ki te \sqrt{3}, ka 3.

$$3\times \frac{25}{3}\pi$$

Me whakakore te 3 me te 3.

$$25\pi$$
