Whakaoti i te 3.14*0.05*(30/2-2)/3((30/2)^2+30*2/2+2^2)

$$\frac { 3.14 \times 0.05 \times ( \frac { 30 } { 2 } - 2 ) } { 3 } ( ( \frac { 30 } { 2 } ) ^ { 2 } + \frac { 30 \times 2 } { 2 } + 2 ^ { 2 } )$$

Aromātai

$$\frac{528619}{3000}\approx 176.206333333$$

Ngā Upane Otinga

Whakareatia te 3.14 ki te 0.05, ka 0.157.

$$\frac{0.157\left(\frac{30}{2}-2\right)}{3}\left(\left(\frac{30}{2}\right)^{2}+\frac{30\times 2}{2}+2^{2}\right)$$

Whakawehea te 30 ki te 2, kia riro ko 15.

$$\frac{0.157\left(15-2\right)}{3}\left(\left(\frac{30}{2}\right)^{2}+\frac{30\times 2}{2}+2^{2}\right)$$

Tangohia te 2 i te 15, ka 13.

$$\frac{0.157\times 13}{3}\left(\left(\frac{30}{2}\right)^{2}+\frac{30\times 2}{2}+2^{2}\right)$$

Whakareatia te 0.157 ki te 13, ka 2.041.

$$\frac{2.041}{3}\left(\left(\frac{30}{2}\right)^{2}+\frac{30\times 2}{2}+2^{2}\right)$$

Whakarohaina te \frac{2.041}{3} mā te whakarea i te taurunga me te tauraro ki te 1000.

$$\frac{2041}{3000}\left(\left(\frac{30}{2}\right)^{2}+\frac{30\times 2}{2}+2^{2}\right)$$

Whakawehea te 30 ki te 2, kia riro ko 15.

$$\frac{2041}{3000}\left(15^{2}+\frac{30\times 2}{2}+2^{2}\right)$$

Tātaihia te 15 mā te pū o 2, kia riro ko 225.

$$\frac{2041}{3000}\left(225+\frac{30\times 2}{2}+2^{2}\right)$$

Me whakakore te 2 me te 2.

$$\frac{2041}{3000}\left(225+30+2^{2}\right)$$

Tāpirihia te 225 ki te 30, ka 255.

$$\frac{2041}{3000}\left(255+2^{2}\right)$$

Tātaihia te 2 mā te pū o 2, kia riro ko 4.

$$\frac{2041}{3000}\left(255+4\right)$$

Tāpirihia te 255 ki te 4, ka 259.

$$\frac{2041}{3000}\times 259$$

Whakareatia te \frac{2041}{3000} ki te 259, ka \frac{528619}{3000}.

$$\frac{528619}{3000}$$

Tauwehe

$$\frac{7 \cdot 13 \cdot 37 \cdot 157}{3 \cdot 2 ^ {3} \cdot 5 ^ {3}} = 176\frac{619}{3000} = 176.20633333333333$$
