A cone-shaped wheat pile is 12.56 meters long and 5 meters long at the bottom. It weighs 735 kg per cubic meter of wheat. How many tons does this pile of wheat weigh? (keep one decimal place)

A cone-shaped wheat pile is 12.56 meters long and 5 meters long at the bottom. It weighs 735 kg per cubic meter of wheat. How many tons does this pile of wheat weigh? (keep one decimal place)

12.56 ﹣ 3.14 ﹣ 2 = 2m
3.14 × 2 & # 178; × 1.5 × 1 / 3 × 735 = 4616.8kg ≈ 4.6t

It's a conical wheat cone. The perimeter of the bottom is 12.56 meters, the height is 2.4 meters, and the weight of each cubic meter of wheat is 735 kg. How many kg is this pile of wheat?
(the number obtained keeps the whole number)

Radius = 12.56 △ 3.14 △ 2 = 2m
Volume = 3.14 × 2 × 2.4 × 1 / 3 = 10.048 M3
Weight = 10.048 × 735 = 7385.28kg ≈ 7385kg
If you understand and solve your problem,

The circumference of the bottom surface of a cone-shaped wheat pile is 12.56 meters, the height is 1.8 meters, and each cubic meter of wheat weighs 735 kg

First, the volume of the cone: bottom circumference = 2 π r = 12.56; so radius r = 2; volume = bottom area * height / 3 = 3.14 * 2 * 2 * 1.8 / 3 = 7.536 cubic meters; flour weight = 7.536 * 735 = 5538.96 kg
