Answer:
No, she used the diameter instead of the radius measure.
Step-by-step explanation:
we know that
The volume of the sphere is equal to

we have
----> the radius is half the diameter
substitute

Step-by-step explanation:
The answer for this would be 23.4.
This is because 1.3 = 1 mile. Therefore you should do 1.3 x 18
which equals 23.4!

Find Slope
--------------------------------------------------
y = -1/3 x + 4
Slope = -1/3
Slope of the parallel line = -1/3
--------------------------------------------------
Insert slope into y = mx + c
--------------------------------------------------
y = -1/3 x + c
--------------------------------------------------
Find y-intercept
--------------------------------------------------
y = -1/3 x + c
at point (6, 5)
5 = -1/3 (6) + c
5 = - 2 + c
c = 5 + 2
c = 7
--------------------------------------------------
Insert y-intercept into y = -1/3x + c
--------------------------------------------------
y = -1/3 x + 7
--------------------------------------------------
Answer: y = -1/3 x + 7 (Answer B)
