Answer:

about 21.9 ft²

Step-by-step explanation:

area of a half circle = $\frac{\pi r ^{2} }{2}$

so $\frac{\pi 3^{2} }{2} = 14.13716694$ ft²

are of a square is $bh\\$

so 6 x 6 = 36 ft²

so the area of the figure would equal the area of the square minus the area of the half-circle

36 ft² - 14.13716694 ft² = 21.86283306 ft² ≈ 21.9 ft²

Find the distance between the following points using the Pythagorean theorem: (-5, 4) and (8, -3)

3241004551 [841]

First, draw a diagram to visualize the situation:

As we can see, the difference between the x-coordinates of the points is the length of one leg of a right triangle, and the difference between the y-coordinates is the length of the other leg.

Then, for the given points (-5,4) and (8,-3), the distance given by the Pythagorean Theorem is:

$\begin{gathered} d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2} \\ \\ =\sqrt{(8--5)^2+(-3-4)^2} \\ \\ =\sqrt{(13)^2+(-7)^2} \\ \\ =\sqrt{169+49} \\ \\ =\sqrt{218} \\ \\ \approx14.7648... \end{gathered}$

Therefore, the distance between the points (-5,4) and (8,-3) is: √218.

An equilateral shape is a shape that has all congruent sides.

Sandy has a greater probability of selecting an equilateral shape

Given

Sandy: Equilateral triangle, Rhombus, and Regular hexagon

Robert: Scalene triangle, Kite, Isosceles trapezoid, Non-special quadrilateral, and Obtuse isosceles triangle

All three shapes in Sandy's shape bucket are equilateral.

So, the probability that Sandy picks an equilateral shape is 1

All five shapes in Robert's shape bucket are non-equilateral.

So, the probability that Robert picks an equilateral shape is 0

By comparing the probabilities:

1 is greater than 0

Hence, Sandy is more likely to pick an equilateral shape than Robert.
