amid [387]

Answer:

Required value is $\frac{1250}{3}$ .

Step-by-step explanation:

We have to find the value of,

$\int\int_{D} x^2y dA\hfill (1)$

where, $D=\{(5,\theta) : 0\leq r\leq 5, 0\leq \theta \leq \pi \}$

To convert it in polar form let $x=r\cos\theta, y=r\sin\theta$ and substitute in (1) we get,

$\int\int_{D} x^2y dA$

$=\int_{0}^{\pi}\int_{0}^{5}(r\cos\theta)^2(r\sin\theta)rdrd\theta$

Assuming,

$u=\cos \theta$ then,

$du=-\sin\theta d\theta\implies-du=\sin\thetad\theta[tex]For [tex]\theta=0, u=1$ and $\theta=\pi$ gives u=-1. Hence,

$\int\int_{D} x^2y dA$

$=\int_{0}^{\pi}\int_{0}^{5}(r\cos\theta)^2(r\sin\theta)rdrd\theta$

$=\int_{1}^{-1}u^2(-du)\int_{0}^{5}r^4dr$

$=\int_{-1}^{1}u^2du\int_{0}^{5}r^4dr$

$=\Big[\frac{u^3}{3}\Big]_{-1}^{1}\times\Big[\frac{r^5}{5}\Big]_{0}^{5}$

$=\frac{2\times 5^4}{3}=\frac{1250}{3}$
