Answer:

$10.71 yd$

Step-by-step explanation:

First let's find the radius of the quarter circle.

$area =\frac{1}{4} \pi {r}^{2} \\ 7.065 = \frac{1}{4} *3.14 {r}^{2} \\ \frac{7.065}{3.14} = \frac{1}{4} * \frac{3.14 {r}^{2} }{3.14} \\ 9 = {r}^{2} \\ \sqrt{9} = r \\ 3 yd= r$

Now let's find the arc length of this quarter circle.

$\frac{90}{360} \times 2\pi \: r \\ \frac{1}{4} \times 2 \times 3.14 \times 3 \\ = \frac{9.42}{4} \\ = 4.71yd \\$

Now let's find the perimeter $perimeter \\ = arc \: \: length + radius + radius \\ = 4.71 + 3 + 3 \\ = 10.71yd$

hope this helps

Quadrilateral A B C D is rotated 145 degrees about point T to form quadrilateral A prime B prime C prime D prime.

Sunny_sXe [5.5K]

The correct answer is option A which is ABCD ≅ A'B'C'D'.

<h3>What is translation?</h3>

The process of changing the location of the image on the coordinate system will be known as the translation.

Quadrilateral ABCD is rotated at 145° about point T. The result is quadrilateral A'B'C'D'.

ABCD ≅ A'B'C'D'is correct Since the quadrilateral remains the same even after rotation of 145 degrees. Its corresponding sides and angles will remain the same.

Thus ABCD is congruent to A'B'C'D'.

The equation of the circle whose center is at (2,1) and the radius is 3 is

-BARSIC- [3]

$\bf \textit{equation of a circle}\\\\ (x- h)^2+(y- k)^2= r^2 \qquad center~~(\stackrel{2}{ h},\stackrel{1}{ k})\qquad \qquad radius=\stackrel{3}{ r} \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ (x-2)^2+(y-1)^2=3^2\implies (x-2)^2+(y-1)^2=9$
