Answer:
2 PI
Step-by-step explanation:
so the segment appears to be 1/4th of the circle, being shown by the pi/2 as displayed. Thus, we can solve for the circumfrence and divide that answer by 4. since 2*pi*r is the way to calculate this problem, it would be 2 times pi times 4, giving us the whole circumfrence of 8pi. Divide that by 4, and you have the solution of 2 pi

<em>Answer:
</em>
<em>Elena's running speed is 5 miles/hour
</em>
<em>Explanation:
</em>
<em>The speed is defined as the covered distance per unit time
</em>
<em>In the problem, we have:
</em>
<em>The distance covered is the length (circumference) of the circular track which is given as of a mile.
</em>
<em>We are also given that she completes each lap (she completes of a mile) in of an hour
</em>
<em>
</em>
<em>To get her speed, we will divide the distance covered by the time taken to cover this distance
</em>
<em>This is done as follows:
</em>
<em>speed = miles/hour
</em>
<em>This means that:
</em>
<em>Elena can run 5 miles each hour</em>
