In one corner of the warehouse, there is rice, a quarter cone, with a bottom arc length of 1.57 meters and a cone height of 2.4 meters. A cubic meter of rice is 725 kg. What's the weight of this pile of rice Within ten minutes, 50. Oh, I'll give you after answering. I have plenty!
Radius 1.57x4 ÷ (2x3.14) = 1m
Volume 1 / 3x1x3.14x2.4 △ 4 = 0.628 M3
Weight 0.628x725 = 455.3kg
If other problems are added,
A cone-shaped grain pile is 1.2 meters high and covers an area of 16 square meters. Put this pile of grain into the granary, which accounts for 27% of the whole granary. Calculate the volume of the granary
13 × 16 × 1.2 △ 27, = 6.4 △ 27, = 22.4 cubic meters; a: the volume of this granary is 22.4 cubic meters
A cone-shaped grain pile, 2 meters, covers an area of 16 square meters. Put this pile of grain into a granary, which just accounts for 2 / 9 of the granary. The volume of the granary is several cubic meters
Upstairs is wrong, it should be like this: 16x1.2x1/3 divided by 2 / 9 = 28.8 (cubic meters)
Answer
The volume formula of cone should be bottom area x Height x 1 / 3~
