Find the perimeter and the area of the composite figure
ankoles [38]

Answer:

Part A) The approximate perimeter of the concrete region is P=64.66\ yd

Par B) The exact area of the concrete region is A=(8\pi+162.4)\ yd^{2}

Step-by-step explanation:

Part A) What is the approximate perimeter of the concrete region?

we know that

The perimeter of the composite figure is equal to

P=\pi r+2(15.2)+ 11.5+10.2

The radius of semicircle is

r=8/2=4\ yd

substitute

P=(3.14)(4)+2(15.2)+ 11.5+10.2=64.66\ yd

Part B) What is the exact area of the concrete region?

we know that

The area of the composite figure is equal to the area of semicircle plus the area of rectangle plus the area of triangle

so

A=\frac{1}{2} \pi r^{2} +(15.2)(8)+\frac{1}{2}(10.2)(8)

The radius of semicircle is

r=8/2=4\ yd

A=\frac{1}{2} \pi (4)^{2} +(15.2)(8)+\frac{1}{2}(10.2)(8)

A=8\pi+121.6+40.8

A=(8\pi+162.4)\ yd^{2}

BRAINLIEST IF CORRECT AND EXPLANATION <br> Solve each equation in the interval [0, 2pi)
victus00 [196]

Answer:  \frac{\pi}{2}, \ \frac{5\pi}{4}, \ \frac{3\pi}{2}, \ \frac{7\pi}{4}

We can write the four solutions as:  pi/2, 5pi/4, 3pi/2, 7pi/4

=============================================================

Work Shown:

\sqrt{2}\cot(x)\sin(x)+\cot(x)=0\\\\\cot(x)\left(\sqrt{2}\sin(x)+1\right)=0\\\\\cot(x)=0 \ \text{ or } \ \sqrt{2}\sin(x)+1=0\\\\\frac{\cos(x)}{\sin(x)}=0 \ \text{ or } \ \sqrt{2}\sin(x)=-1\\\\\cos(x)=0*\sin(x) \ \text{ or } \ \sin(x)=\frac{-1}{\sqrt{2}}\\\\\cos(x)=0 \ \text{ or } \ \sin(x)=\frac{-\sqrt{2}}{2}\\\\

Use the unit circle or reference sheet to find that \cos(x)=0 leads to x = \frac{\pi}{2} \ \text{ and } \ x =  \frac{3\pi}{2} when working with the interval [0,2pi)

Also, use of the unit circle would show that \sin(x)=\frac{-\sqrt{2}}{2} leads to x = \frac{5\pi}{4} \ \text{ and } \ x =  \frac{7\pi}{4} when working with the interval [0,2pi)

-----------

Overall, the four solutions on the interval [0, 2pi) are

\frac{\pi}{2}, \ \frac{5\pi}{4}, \ \frac{3\pi}{2}, \ \frac{7\pi}{4}

To verify these solutions, plug them in one at a time into the original equation. You should end up with 0 = 0 after simplifying. Make sure your calculator is in radian mode.
