A picture shows the net of the lateral surface of the cone. Which statement about this cone is NOT true?

Brut [27]

Answer:

Area of the Net is incorrect

Step-by-step explanation:

Base Surface Area = π×12^2

= 452.38934211693 inches^2

Lateral Surface Area = π×12×√12^2 + 15^2

= 724.1762903163 inches^2

Total Surface Area = 1176.5656324332 inches^2

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

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

Answer:

I'm not to sure but I think it's A, 38.4 mph. By the way are you from Bay doing this for spring break math hw?

Step-by-step explanation:

12/3.75 is 3.2; 3.2*12 is 38.4. do 12/3.75 meaning 3.2 miles every hour multiplied by 12 to get 38.4 miles.
