A cone-shaped sand pile has a perimeter of 25.12m at the bottom and 1.49t/m3 of sand. How many times can a 5-ton truck be used to transport it

A cone-shaped sand pile has a perimeter of 25.12m at the bottom and 1.49t/m3 of sand. How many times can a 5-ton truck be used to transport it

Bottom radius 25.12 △ 2 △ 3.14 = 4
Sand pile volume = 3.14 × 4 & # 178; × 3 △ 3 = 50.24 M3
The weight of sand pile is 50.24 × 1.49 ≈ 75 tons
75 △ 5 = 15 times
It will be transported 15 times by 5-ton truck
