seropon [69]
11*2 = 22 (calculating the diameter)

Using πD for the area:
π * 22 = 22π

Getting 3/4 of the area because the dog can not move past the corners of the garage;

22π * 3/4 = 16.5π

Getting the answer in feet^2:
16.5 * 3.14 = 51.84 feet^2

Hope this helps! :)

Answer:

<em>The helicopter is 27.38 m far off the ground</em>

Step-by-step explanation:

The drawing shown in the image below has all the measures and variables needed to solve the problem.

We need to find R, the height of the helicopter. We'll use the law of sines to find the length of side a.

\displaystyle \frac{28}{\sin X}=\frac{a}{\sin 54^\circ}

The angle X is the measure needed to complete 180°:

X = 180° - 54° - 62° = 64°

Solving for a:

\displaystyle a=\frac{28}{\sin 64^\circ}\cdot \sin 54^\circ

Calculating:

a = 31.11 m

Now using the sine ratio in the right triangle to the left side:

\displaystyle \sin 62^\circ=\frac{R}{a}

Solving for R:

R=a\sin 62^\circ

R=31.11*0.88

R = 27.38 m

The helicopter is 27.38 m far off the ground
