A cone-shaped sand pile is 15.7 meters in circumference at the bottom and 2.4 meters in height. If the sand weight per cubic meter is 1.5 tons, how many tons more is the sand weight

1.5*3.14*(15.7/(3.14*2))*(15.7/(3.14*2))*2.4/3=23.55
Mass per cubic meter * π * square of radius * height / 3 = mass obtained
