Given that value of 220. You know the radius. Now use sin function to evaluate the high.
And then the pyramid formula to get the volume...
A construction company wants to know how much sand is in a pile. The company measures that the distance from the edge of the pile at ground level to the very top of the pile is 55 ft. The company also measures that the distance around the pile at ground level is 220 ft.
a.) How much sand is in the pile?
b.) The construction company has trucks that carry 10 cubic yards in each load. How many loads will it take to move the pile of sand? Explain
for a i came up with 54454.2 cubic feet and then for b i got 202 truck loads. I am not sure if they are right, but can someone please try this and give me some feedback??? Is one cubic yard equal to 27 cubic feet?
I understand. I calculated the answer, I am just not sure if i did it correctly. I got the radius to be 110/pie and the height of the cone (its not a pyramid) to be the square root of (3025-(12100/piesquared))
a. 54454.2 cubic feet
b. 202 truck loads
I am not sure if my answers are right...thats why i posted...hoping someone else would also do the problem, so we could compare answers.
does one cubic yard equal 27 cubic feet?
