A cone-shaped wheat pile has a circumference of 18.84 meters at the bottom and a height of 2 meters. If each cubic meter of wheat weighs about 750 kg, how many kg does the pile weigh?

A cone-shaped wheat pile has a circumference of 18.84 meters at the bottom and a height of 2 meters. If each cubic meter of wheat weighs about 750 kg, how many kg does the pile weigh?


18.84 △ 3.14 △ 2 = 3 (m); 3.14 × 32 × 2 × 13 × 750, = 3.14 × 9 × 2 × 13 × 750, = 3.14 × 6 × 750, = 14130 (kg); a: this pile of wheat weighs about 14130 kg



The staff measured that the perimeter of the bottom is 18.84m and the height is 4m. It is known that the weight of corn is 750KG per cubic meter. How much is the weight of corn?


The volume is (1 / 3) x3.14 (18,84 / 2 / 3.14) square X4 = 37.68 cubic meters
The weight is 37.68x750 = 28260kg



There is a cone corn pile on the sun field. One cubic meter of corn weighs about 0.75 tons. It is 0.9 meters high and 25.12 meters in circumference. It is transported by a 5-ton truck


There is a cone corn pile on the sun field. One cubic meter of corn weighs about 0.75 tons. Its height is 0.9m and its bottom circumference is 25.12m. How many times does it need to transport these corn with a 5-ton truck?
Radius 25.12 △ 3.14 △ 2 = 4m
Volume 3.14 × 4 × 4 × 0.9 × 1 / 3 = 15.072 M3
0.75 × 15.072 △ 5 = 2.2608 times ≈ 3 times (progressive method)
