There is a cone-shaped gravel pile, the perimeter of the bottom is 12.56, and the height is 0.6. If each cubic stone weighs 2 tons, how many tons does the pile weigh? It's a formula. It's a speed!

There is a cone-shaped gravel pile, the perimeter of the bottom is 12.56, and the height is 0.6. If each cubic stone weighs 2 tons, how many tons does the pile weigh? It's a formula. It's a speed!

Bottom radius = 12.56 △ 3.14 △ 2 = 2 (m)
Bottom area = 3.14 × 2 & # 178; = 12.56 (M2)
Volume = 1 / 3 × 12.56 × 0.6 = 2.512 (M3)
The weight of this pile of gravel is about 2.512 × 2 = 5.024 (tons)
