The area of the shaded region is option first is correct.
It is given that a circle is inscribed in a regular hexagon with sides of 10 feet.
It is required to find the shaded area (missing data is attached shown in the picture).
<h3>What is a circle?</h3>It is defined as the combination of points that and every point has an equal distance from a fixed point ( called the center of a circle).
We have a hexagon with a side length of 10 feet.
We know the area of the hexagon is given by:
where a is the side length.
⇒
We have the shortest length = x feet and from the figure:
2x = 10
x = 5 feet
The radius of the circle r = longer leg
feet
The area of the circle a = ⇒
The area of the shaded region = A - a
Thus, the area of the shaded region is

Answer:
y = 3, TU = 6
Step-by-step explanation:
SU is an angle bisector and divides the opposite side into segments that are proportional to the other 2 sides, that is
=
, substitute values
=
( cross- multiply )
14.4(4y - 2) = 48y
57.6y - 28.8 = 48y ( subtract 48y from both sides )
9.6y - 28.8 = 0 ( add 28.8 to both sides )
9.6y = 28.8 ( divide both sides by 9.6 )
y = 3
Then
TU = 2y = 2 × 3 = 6
