Companies that manufacture canned goods use surface area every day! Each can will need a wrapper to indicate what it is they're holding, and each wrapper just so happens to be the lateral area of a cylinder. Every winter, Christmas rolls around and it can seriously save paper and energy if you found the surface area of your gift prior to wrapping it. That way you can cut out the exact amount of paper without having uneven sides that will eventually need trimming, or sizes that don't fit. Hope this helps!

IrinaK [193]

Answer:

Step-by-step explanation:

160miles • 330miles= 52,800square miles

Now it wants the population density in people per square miles, so you need to divide the population by the number of square miles.

4779736/52800=90.5 which is about 91people per square mile.

Find the surface area of the surface given by the portion of the paraboloid z=3x2+3y2 that lies inside the cylinder x2+y2=4. (hi

natta225 [31]

Parameterize the part of the paraboloid within the cylinder - I'll call it $S$ - by

$\mathbf r(u,v)=\langle x(u,v),y(u,v),z(u,v)\rangle=\left\langle u\cos v,u\sin v,3u^2\right\rangle$

with $0\le u\le2$ and $0\le v\le2\pi$ . The region's area is given by the surface integral

$\displaystyle\iint_S\mathrm dS=\int_{u=0}^{u=2}\int_{v=0}^{v=2\pi}\|\mathbf r_u\times\mathbf r_v\|\,\mathrm du\,\mathrm dv$
$=\displaystyle\int_{v=0}^{v=2\pi}\int_{u=0}^{u=2}u\sqrt{1+36u^2}\,\mathrm du\,\mathrm dv$
$=\displaystyle2\pi\int_{u=0}^{u=2}u\sqrt{1+36u^2}\,\mathrm du$

Take $w=1+36u^2$ so that $\mathrm dw=72u\,\mathrm du$ , and the integral becomes

$=\displaystyle\frac{2\pi}{72}\int_{w=1}^{w=145}\sqrt w\,\mathrm dw$
$=\displaystyle\frac\pi{36}\frac23w^{3/2}\bigg|_{w=1}^{w=145}$
$=\dfrac\pi{54}(145^{3/2}-1)\approx101.522$
