Answer: 157 truckloads
Step-by-step explanation:
To calculate how many truckloads the company will need, we first need to calculate how many cubic yards of limestone there is.
We can calculate the volume of the limestone using the formula for the volume of a cone since the problem states that the pile is shaped like a cone. The formula for the volume of a cone is given as:
[tex]V = \frac{1}{3} \pi r^{2} h[/tex], where:
- V represents the volume of the cone
- r represents the radius of the base of the cone
- h represents the height of the cone
The dimensions we are given are:
- The radius (r) is 9 yards
- The height (h) is 13 yards
Plugging these values into the formula and using 3.14 for π:
[tex]V = \frac{1}{3} (3.14)(9)^{2} (13)[/tex]
V = 1102.14 cubic yards of limestone
Since we have calculated the volume of the limestone, we need to calculate how many truckloads the company will need. To do this, we can divide the total amount of limestone by how much limestone each truckload holds.
It is given that each truckload holds 7.03 cubic yards of limestone.
1102.14 ÷ 7.03 = 156.7766714
Since it is not possible to have a fraction of a truckload, we need to round 156.7766714 up to the nearest integer.
Therefore, the company will need 157 truckloads.
