ANSWER
The length of a Diameter is 3.714
EXPLANATION
The circumscribed triangle is shown in the attachment.
We use the cosine ratio to find the altitude of the isosceles triangle.


Altitude =8cos(60°)
Altitude=4cm
Let the upper half of the altitude be y cm.
Then the radius of the circle is (y-4)cm
The upper radius meets the tangent at right angles.
From the smaller right triangle,






y=1.857
The diameter is 2y

=2(1.875)
The length of a Diameter is 3.714
Your answer is D. You just take the feet in a mile (5,280) and divide it by his pace (2.75) feet. You get 1920, which is your answer.
Answer:

Step-by-step explanation:

Add 6 to both sides:


Divide both sides by -3:


Subtract 4 from both sides:


Divide both sides by 2:
