SILOS. 195 



cows, that are to be fed 40 pounds each daily for 180 

 days ? 



Process : 

 1st part. 25 X 40 X 180 -r- 2,000 = 90, tons required. 



25 X 5 sq. ft. = 125 sq. ft., horizontal feeding surface. 



125 -f- .7854 = 159.15 



V159.15 12.6, diameter of the silo in feet. 

 2nd part. 1 ton occupies 50 cubic feet. 



90 tons occupy 4,500 cubic feet. 



4,500 -i- 125 = 36 feet, height of silo. 



700. What should be the diameter and height of a 

 round silo for a herd of 25 cows that are to be fed 30 

 pounds each daily for 150 days ? 



701. What should be the diameter and height of a 

 round silo for a herd of 25 cows that are to be fed 40 

 pounds daily each for 90 days and 30 pounds each for 80 

 days ? 



702. What should be the diameter and height of a silo 

 for a herd of 40 cows that are to be fed 40 pounds each 

 daily for 160 days ? 



703. What should be the size of a silo for a herd of 60 

 cows that are to be fed 35 pounds each daily for 175 days ? 



704. A round silo has a diameter of 20 feet and a 

 height of 35 feet; how many tons of silage will it hold? 



Process : 



20 X 20 X 0.7854 = 314.16, area of base. 



314.16 X 35 = 10,995.6 cubic feet. 

 10,995.6 -r- 50 = 219.9 tons, capacity of silo. 



705. How many tons of silage will a silo hold that has 

 a diameter of 15 feet and a height of 28 feet ? 



706. What is the capacity of a round .silo 24 feet high 

 and 16 feet in diameter ? 



707. What is the difference in capacity between two
