Answer:
The segment is 6 units long. 
Step-by-step explanation:
The points (–2, 4) and (–2, –2) are vertices of a heptagon. We have to explain how to find the length of the segment formed by these endpoints.
If two points at the ends of a straight line PQ are P( ) and Q(
) and Q( ), then the length of the segment PQ will be given by the formula
), then the length of the segment PQ will be given by the formula  
 
Now, in our case the two points are (-2,4) and (-2,-2) and the length of the segment will be  
 units. (Answer)

Answer:
2
Step-by-step explanation:
You are right as rain. You go to the x axis. 
Find x = 3.5
f(3.5) is the y value of x = 3.5
f(3.5) = 2
It might help you a bit if you wrote it as a point (3.5,2)

Answer:
here, Area of s circle is given by;
A=πr²
but, A=1256.00 sq feet and π=22/7
thus, r=√(A/π)
⇒r=√(1256.00/3.142857143)
thus, r=399.64feet
