Answer: 
Step-by-step explanation:
Since you indicate that it is a cone, you need to use the formula for calculate the volume of a cone. This is:

Where "r" is the radius and "h" is the height of the cone.
According to the information given in the exercise, the height and the radius of the pylons are the following:

Then, knowing these values, you can substitute them into the formula,as following:

Finally, evaluating, you get that the volume of concrete that Tobias will need for each pylon is the one shown below:

100 cm = 1 meter
210 cm = 2.1 meters (multiply both sides by 2.1)
Mary uses 2.1 meters of thread so far, meaning she has 10-2.1 = 7.9 meters left
7.9 meters = (7.9 m)*(100 cm/1 m) = 790 cm
--------------------------------------
Alternate route:
10 meters = (10 m)*(100 cm/1 m) = 1000 cm
Mary uses 210 cm out of 1000 cm total, so she has 1000-210 = 790 cm left.
--------------------------------------
<h3>Answer: 790 cm</h3>
