SILOS. 195 



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

 days ? 



Process: 



1st part. 25 X 40 X 180 -i- 2,000 = 90 Tons required. 



25X5 sq. ft. = 125 sq. ft Horizontal feeding 



surface. 

 125^.7 854 = 159.15 



^159.15 = 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 H- 125 = 36 Feet, height of silo. 



700. Wliat 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. \\'hat should be the diameter and height of a 

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

 80 days? 



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

 for a herd of 40 cows that arc 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 1T5 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 Area of base. 



314 X 35 = 11,000 Cubic feet. 



11,000 ^ 50 = 220 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
