A cone-shaped rice pile has a base circumference of 6.28m and a height of 0.45M. If each cubic meter of rice weighs 550Kg, is there a ton of rice in this pile?

A cone-shaped rice pile has a base circumference of 6.28m and a height of 0.45M. If each cubic meter of rice weighs 550Kg, is there a ton of rice in this pile?


Bottom radius = 6.28 △ 3.14 △ 2 = 1m
Volume = 1 × 1 × 3.14 × 0.45 × 1 / 3 = 0.471 M3
Mass = 0.471 × 550 = 259.05kg
There is not a ton of rice in this pile



A cone-shaped rice pile has a circumference of 18.84 meters at the bottom and weighs about 0.6 tons per cubic meter. How many tons does this pile weigh?


Bottom radius 18.84 ÷ (2x3.14) = 3M
Volume 1 / 3x3.14x3 = 28.26m3
Weight 28.26x0.6 = 16.956 tons



The circumference of the bottom surface of a cone-shaped rice pile is 18.84 meters and 5 meters. If each cubic meter of rice weighs 0.85 tons, how many tons does this pile of rice weigh


Bottom radius = 18.84 △ 3.14 △ 2 = 3M
Volume = 3.14x3 & # 178; X1.5 △ 3 = 14.13m3
Weight = 0.85x14.13 = 12.0105 tons
