Answer:
12
Step-by-step explanation:


When F = 18; d = 2


Cross multiply;
18 x 4 = K
72 = K
There the equation connecting F and
is

Now, Find F when d = 6
All you do is to substitute d = 6 in to 

Therefore;
F = 12
Please mark me brainiest if correct.
0.25 is going to be the unit rate when -x in the equation is considered to be 1

Step-by-step explanation:
i just took it on edge
Assuming your numbers are rounded to the nearest km, the minimum area will be ...
(5.5 km)·(10.5 km) = 57.75 km² . . . minimum
And the maximum area will be ...
(6.5 km)·(11.5 km) = 74.75 km² . . . maximum
_____
When a number is rounded to 6 km as the nearest km, its value may actually be anywhere in the range 6 km ± 0.5 km. If you really want to get technical about it, the ranges of possible dimensions are [5.5, 6.5) km and [10.5, 11.5) km, and the range of possible areas is [57.75, 74.75) km².
We know that the volume of a sphere is:

we need half of this, so we use:
