Area of the square is 144m.
Area of the circle is 113.1m.
Subtract A of circle from A of Square which equals 30.9meters. That is your answer.
If you want I can teach you step by step just comment if you want me to...
Answer:
70
Step-by-step explanation:
Dividing is multiplying by the reciprocal.
So 30 divided by 1/2
is like 30(2)=60
Then add 10 so 60+10=
70
11/8 or 13/8 is the answer.
Answer:44
Step-by-step explanation:44
The horizontal distance between the two balloons is 53.8 meters.
<u><em>Explanation</em></u>
According to the below diagram, A and B are the positions of two balloons which are 48.2 meter and 61.0 meter above the ground respectively.
Horizontal distance between two balloons is AC, which is
meter.
A person in the left balloon observes that the right balloon is 13.38° above the horizontal. That means, ∠BAC = 13.38°
According to the diagram, ![BC= 61.0-48.2 = 12.8 meter](https://tex.z-dn.net/?f=BC%3D%2061.0-48.2%20%3D%2012.8%20meter)
Now in right angle triangle ABC.....
![tan(13.38)=\frac{BC}{AC}\\ \\ tan(13.38)= \frac{12.8}{x} \\ \\ x= \frac{12.8}{tan(13.38)}=53.8](https://tex.z-dn.net/?f=tan%2813.38%29%3D%5Cfrac%7BBC%7D%7BAC%7D%5C%5C%20%5C%5C%20tan%2813.38%29%3D%20%5Cfrac%7B12.8%7D%7Bx%7D%20%5C%5C%20%5C%5C%20x%3D%20%5Cfrac%7B12.8%7D%7Btan%2813.38%29%7D%3D53.8)
So, the horizontal distance between the two balloons is 53.8 meters.
