Answer:
The distance between 240 and 0 is 240
Step-by-step explanation:
You can find the distance between two values by getting it's absolute value.
You can setup the equation like this:
| 0-240 |
When you solve the equation you will find the absolute distance between 240 and 0.

H/1000 = tan(65°)
h = 1000*tan(65°) ≈ 2145 . . . . ft
The helicopter is about 2145 ft high.
Answer:
56.549 cm (choice 1)
Step-by-step explanation:
If the area of the square if 36 cm, then each side is 6 cm.
That means the diameter for each semi circle is also 6 cm.
Formula for a semi circle is 1/2(πr²)
We need the radius, which is half the diameter. So the radius is 6÷2= 3
Now plug in to the formula.
A= 1/2(π3²)
A= 14.137 (nearest hundredths)
Now multiply that by 4, because there are 4 semi circles
4(14.137)= 56.549 cm (nearest hundredths)
