Since x/9•4 is a multiple step problem you could do it one of two ways you could either divide 4 since you are multiplying four or you can multiply by nine since you are dividing by nine

Evaluate the following integral over the specified region. Assume (r comma theta )(r,θ) are polar coordinates. ModifyingBelow In

topjm [15]

Answer:

Step-by-step explanation:

We have to integrate the function

$16+x^2+y^2$ over the region

$1\leq r\leq 3\\0\leq \theta \leq \pi$

Let us convert into polar coordinates

x=cost : y = sint

Then we get dxdy = rdr dt

So we get the integral as

$\int \int _R (16+x^2+y^2)^2 dxdy\\= \int\limits^3_0 \int\limits^\pi_0( {16+r^2}^2) (r)drdt\\ =(t) (\frac{(16+r^2)^3}{6}$

Substitute the limits to get

Answer

= $(\pi-0) [\frac{1}{6} (25-16)\\=1.5 \pi$
