We know the length and width. We're just  trying to find all of the area in between. To find area, we do length*width. Length is 11.5 and the width is 10.75. 11.5*10.75=123.625 ft^2

Lets get started :)


The First question:
Diameter = 20 ft
Radius = \frac{1}{2} of 20 (diameter) = 20 ft

Area formula of a circle is
A = \pir²
    =\pi(10)²
    =100\pi ft²
    ≈ 314 ft²

The answer will be the second option

The Second question:
radius of circle = 12mm  divided into 20 sectors area

A = \pir²
   = \pi(12)²
   = 144\pi ft²

Divide into 20 equal sector areas = \frac{144 \pi }{20} = 7.2 \pi

≈ 22.6 mm²

Your answer will be the third option

The Third Question:

90°, sector area = 36\pi , Radius = ?

\frac{angle}{360} = \frac{sector}{ \pi (r)^2}
\frac{90}{360} = \frac{36 \pi }{ \pi r^2}
\pi and \pi cancels out

We can now cross multiply
360 × 36 = 90r²
12960 = 90r²

Divide by 90 on either side

\frac{12960}{90} = \frac{90r^2}{90}
144 = r²

Take squareroot 
 \sqrt{144} = x
x = 12 in

Your answer will be the third option

What is the image of point (4, 3) if the rotation is -270º ?
Ludmilka [50]

Answer:

OK so you point is y=4 and x=3 so plot that on a x,y graph. Then to turn it -270 degrees you need to clock wise. normally you would just go counter clock wise but since your rotation is negative you go counter clock wise. hope this helped!!

Rewrite –220° in radians. Write the solution as a fraction in simplest form.
son4ous [18]

Answer:

- \frac{11\pi }{9}

Step-by-step explanation:

To convert degrees to radians

radian measure = degree measure × \frac{\pi }{180} , then

radian measure = - 220 × \frac{\pi }{180} ( divide 220 and 180 by 20 )

                           = - \frac{11\pi }{9}
