Answer:
7 km
Step-by-step explanation:
Substitute:
The equation for area of a semi-circle is
A =
76.97 =
Multiply by 2 on both sides:
2(76.97) = ( )2
153.94 =
Divide by pi on both sides:
153.94 =
/pi /pi
49.03 ≈
Find the square root:
7 = r
For 1–3, find the area of each circle. Use 3.14 for π. Round to the nearest tenth if necessary.

For this case we have that the main function is given by:
We apply the following transformation:
Vertical displacements:
Assume k> 0
To graph y = f (x) - k, move the graph k units down.
For k = 3 we have:
Answer:
when the function is changed to f (x) - 3 the change that will occur is:
Vertical displacement 3 units down.
