Answer:
Option C is correct.

Step-by-step explanation:
Let x be the distance cover by Michelle
Given:
A circle diameter is 3 miles.
And Michelle biked around the trail 4 times.
We know that
The circumference of a circle.
circumference =  ----------(1)
----------(1)
where 
 miles
 miles
Put  and r value in equation 1.
 and r value in equation 1.


The circumference of a circle is 9.42 miles.
And Michelle biked 4 times, that is equal to 4  circumference.
 circumference.

 .
.
That is equal to 38 miles.
Therefore, Michelle biked around 4 trail is 38 miles.
 
        
             
        
        
        
Answer:
(4+8)(4) = (x) 3
Step-by-step explanation:
The picture shows two secants intersecting at a point outside the circle.  A beautiful pattern for this is:  along each secant, the product (multiply) the <em>entire</em> secant by the <em>outside</em> part is the same.
(entire secant)(outside part) = (entire secant)(ouside part)
(4+8)(4) = (x)(3)
