A cone-shaped wheat pile has a circumference of 6.28 meters at the bottom and a height of 4.5 meters. How many meters is the height of the wheat when it is put into a cylindrical grain bin with a radius of 2 meters at the bottom?
Radius = 6.28 ÷ (2 * 3.14) = 1
3.14 * 1 * 4.5 * 1 / 3 (3.14 * 2 * 2) = 0.375 M
The perimeter of the bottom surface of a cone-shaped wheat pile is 15.7 meters and 8 meters. Put the wheat into a cylindrical grain bin, which is just full. The height of the grain bin is 1.5 meters. What's the area of the bottom of the cylinder
15.7 ﹣ 3.14 ﹣ 2 = 2.5 this is the radius
2.5 × 2.5 × 1.8 △ 3 = 3.75 this is the volume of the cone
3.75 △ 2.5 = 1.5 this is the area of the bottom of the cylinder, which is the floor area
The perimeter of the bottom of a cone-shaped wheat pile is 15.7 meters and the height is 1.8 meters. If the wheat is put into a cylindrical grain bin, it only accounts for one fourth of the volume of the grain bin
Bottom radius of conical wheat pile = 15.7 △ 3.14 △ 2 = 2.5 (m)
Bottom area of conical wheat pile = 2.5 m ﹥ 178; × 3.14 = 19.625 (m ﹥ 178;)
The volume of cone wheat pile = 19.625 × 1.8 △ 3 = 11.775 (m # 179;)
The volume of cylindrical beam container = 11.775 × 4 = 47.1 (m # 179;)
Height of cylindrical beam container = 47.1 △ 10 = 4.71 (m)
