Answer:

B. 20.2 in²

Step-by-step explanation:

First you find the area of the whole rectangle, which would be base × height, or 5 × 6.

Area of the rectangle is 30

Now you must find the area of the half circle with the formula: A= 1/2 π r²

r represents the radius. 5 is the diameter of the circle, which is double the radius. Hence, the radius is 2.5

Next you can plug in 2.5 in the formula

A= 1/2 π (2.5)²

A= 1/2 π (6.25)

A= 1/2 (19.63)

A= 9.8

Now that you have both areas, subtract the area of the semicircle from the area of the rectangle to get the area of the shaded region.

30 - 9.8 = 20.2

Evaluate the line integral using the fundamental theorem of line integrals. use a computer algebra system to verify your results

mario62 [17]

$\dfrac{\partial f}{\partial x}=\cos x\sin y\implies f(x,y)=\sin x\sin y+g(y)$

$\dfrac{\partial f}{\partial y}=\sin x\cos y=\sin x\cos y+\dfrac{\mathrm dg}{\mathrm dy}$
$\implies\dfrac{\mathrm dg}{\mathrm dy}=0\implies g(y)=C$

$f(x,y)=\sin x\sin y+C$

$\displaystyle\int_{\mathcal C}\cos x\sin y\,\mathrm dx+\sin x\cos y\,\mathrm dy=\int_{\mathcal C}\mathbf f\cdot\mathrm d\mathbf r=f\left(\frac{3\pi}2,\frac\pi2\right)-f(0,-\pi)=-1$
