Use the net to determine the total surface area. Please help ASAP

Mathematics
1 answer:
wariber [46]3 years ago

Answer:

C.  S.A. = 340.8 cm^{2}

Step-by-step explanation:

Area of rectangles = 6x 12 = 72 cm^{2}

all three have the same area - 72 x 3 = 216 cm^{2}

Area of triangle = 10.4 x 12 ÷ 2

Since there are 2 trignles - 10.4 x 12 = 124.8 cm^{2}

Add all sides up

S.A. = 216 cm^{2} + 124.8 cm^{2}

S.A. = 340.8 cm^{2}

Make a sketch of the region and its bounding curves. Find the area of the region. The region inside one leaf of r
Anastaziya [24]

The region inside one leaf of r the area of the region is pi.20.

r =cos5θ

cos5θ =0

5θ=pi/2 ,5θ=3pi/2

θ=pi/10,θ=3pi/10

area of one leaf = ∫[pi/10 to 3pi/10](1/2)r2dθ

= ∫[pi/10 to 3pi/10](1/2)(cos5θ)2dθ

= ∫[pi/10 to 3pi/10](1/4)(1+cos10θ)dθ

=[pi/10 to 3pi/10](1/4)(θ+ (1/10)sin10θ)

=(1/4)((3pi/10)+ (1/10)sin3pi) -(1/4)((pi/10)+ (1/10)sinpi)

=(1/4)(3pi/10)  -(1/4)(pi/10)

=(1/4)(2pi/10)  

=pi/20

area of one leaf =pi.20.

Region area (calculus) Region area. The non-negative function given by y = f(x) represents a smooth curve on the closed interval [a, b].The area through the curve of f(x), the x-axis, and the perpendicular lines x = a and x = b The bounding region shown in Figure 1 is given by.

Et f(x, y, z) = z tan−1(y2)i + z3 ln(x2 + 5)j + zk. find the flux of f across s, the part of the paraboloid x2 + y2 + z = 11 tha
nignag [31]
Since the surface is closed, and the vector field is rather complicated, you can use the divergence theorem. The flux of \mathbf f(x,y,z) across S is given by a surface integral, which the divergence theorem asserts is equivalent to a volume integral:

\displaystyle\iint_S\mathbf f\cdot\mathrm d\mathbf S=\iiint_R(\nabla\cdot\mathbf f)\,\mathrm dV

where R denotes the space with boundary S. We have

\nabla\cdot\mathbf f(x,y,z)=\dfrac{\partial z\tan^{-1}(y^2)}{\partial x}+\dfrac{\partial z^3\ln(x^2+5)}{\partial y}+\dfrac{\partial z}{\partial z}=0+0+1=1

So in fact the flux across S happens to be equal (in magnitude) to the volume encased by S.

\displaystyle\iint_S\mathbf f\cdot\mathrm d\mathbf S=\int_{x=-3}^{x=3}\int_{y=-\sqrt{9-x^2}}^{y=\sqrt{9-x^2}}\int_{z=2}^{z=11-x^2-y^2}\mathrm dz\,\mathrm dy\,\mathrm dx

Convert to cylindrical coordinates, setting

\begin{cases}x=r\cos\theta\\y=r\sin\theta\\z=\zeta\end{cases}\implies\mathrm dV=\mathrm dx\,\mathrm dy\,\mathrm dz=r\,\mathrm dr\,\mathrm d\theta\,\mathrm d\zeta

\displaystyle\iint_S\mathbf f\cdot\mathrm d\mathbf S=\int_{\theta=0}^{\theta=2\pi}\int_{r=0}^{r=3}\int_{\zeta=2}^{\zeta=11-r^2}r\,\mathrm d\zeta\,\mathrm dr\,\mathrm d\theta
=\displaystyle2\pi\int_{r=0}^{r=3}r(11-r^2-2)\,\mathrm dr
=\displaystyle2\pi\int_{r=0}^{r=3}(9r-r^3)\,\mathrm dr=\dfrac{81\pi}2
