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 perimeterperimeter \\  = arc \:  \: length + radius + radius \\  = 4.71 + 3 + 3 \\  = 10.71yd

Answer:

Please find attached the required box and whiskers plot

Step-by-step explanation:

The numbers are given in arranged order as follows;

14, 14, 16, 16, 17, 17, 18, 20, 21, 23

The five number summary are;

The minimum value = 14

The maximum value = 23

The first quartile, Q₁, is the (n + 1)/4th term or the 2.75th term  = 14 + 0.75×(16 - 14) = 15.5

The second quartile, Q₂, (the median) is the  (n + 1)/2th term or the 5.5th term = 17

The third quartile, Q₃, is the  3(n + 1)/4th term or the 8.25th term  = 20 + 0.25×(21 - 20) = 20.25.
