Answer: 11.6

--------------------------------------

Explanation:

See the attached image for a visual reference

The distance from point D to E is 21 units. Point C is the midpoint, so CD is 10.5 units long (21/2 = 10.5)

We have a right triangle ACD. The legs are
AC = 5
CD = 10.5
The hypotenuse is
AD = x
Because AD is another radius of the same circle

Use the pythagorean theorem to find x
a^2 + b^2 = c^2
5^2 + 10.5^2 = x^2
25 + 110.25 = x^2
135.25 = x^2
x^2 = 135.25
x = sqrt(135.25)
x = 11.629703349613
which rounds to 11.6 when rounding to the nearest tenth (one decimal place)

THE RIGHT ANSWERRRRRR

Mkey [24]

Area of semicircle = 1/2 the area of a circle:
$A_{sc}=\frac{1}{2} \pi r^{2}$
radius is half the diameter of 6ft.
$A_{sc} = \frac{1}{2} \pi (3^{2} )=14.13 ft^{2} .$
Area of the rectangle:
$A_{r} =lw=15*6=90 ft^{2} .$
Add the two together:
90 + 14.13 = 104.13
Round to the nearest tenth (one decimal place)
Area = 104.1 square feet.
