The length of the fencing corresponds to the length of the perimeter of the garden:
We also know that the perimeter of a circle is given by:
where r is the radius of the circle.
Putting together the two equations, we have
from which we can find r, the radius of the garden:
The distance from the satellite to the Earth's horizon is 6398 km
<h3>
Pythagoras theorem</h3>
Pythagoras theorem is used to show the relationship between the sides of a right angled triangle. It is given by:
Hypotenuse side² = Adjacent side² + Opposite side²
Let x represent the distance from the satellite to the Earth's horizon
Hence:
- x² = 6370² + 600²
- x² = 40936900
- x = 6398 km
The distance from the satellite to the Earth's horizon is 6398 km

Answer:
-13.2
Step-by-step explanation:
-8.2-5 essentially means that you just have to add 8.2 and 5. (disregard the signs for a moment) if you add them you get 13.2 as both of these number have a negative sign just add it and here's your answer
Answer: ?
