Answer : The length of the wire is, 8533 cm
Step-by-step explanation :
As the iron sphere is beaten and drawn into a wire. That means, their volume will be equal.
Volume of iron sphere = Volume of cylindrical wire
The formula will be:

where,
= radius of sphere = 
= radius of cylindrical wire = 
h = height of cylindrical wire or length of wire
Now put all the given values in the above formula, we get:




Therefore, the length of the wire is, 8533 cm
X = total miles run
4.6 + 0.78 + 3.4 = x
8.78 = x......so he ran a total of 8.78 miles
