Answer: what???
Step-by-step explanation:
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.
Area of circle = pi r^, (r)radius is half the diameter so 9÷2=4.5 so in this scenario it would be 3.14×4.5^
3.14×4.5×4.5=63.6
circumference of circle= diameter×pi (3.14)
so 9×3.14=28.3
C I think because the lines intercept at a common point
Distance formula: SR (A^2+B^2)
SR [(2+9i)^2 + (2-4i)^2] =
SR [4 + 18i + 81i^2 + 4 - 8i + 16i^2] =
SR [8 + 10i + 97i^2]
