Step-by-step explanation: First we will calculate the volume of the cylindrical pillar. We use the formula:
πr^2h.
Where:
π = 3.14
r = 6m
h = 4m.
We calculate thus:
3.14 X 6^2 x 4
= 452.16m^3.
Having gotten the volume of the pillar. We proceed to calculate the cost. We have the cost as $82 per cubic meter, and the pillar is 452.16 cubic meters. We therefore multiply the volume of the pillar by the cost per cubic meter, thus:
82 X 452.16 = 37,077.12
Therefore it costs $37,077.12 to build the concrete pillar.
