Answer:
Explanation:
Since the pile of sand is conical, we would apply the formula for determining the volume of a cone which is expressed as
Volume = 1/3 × πr²h
Where
r represents the radius of the cone.
h represents the vertical height of the cone.
π is a constant whose value is 3.14
From the information given,
Diameter = 18 feet
Radius = Diameter/2 = 18/2
Radius = 9 feet
Height = 10 feet
Therefore,
Volume = 1/3 × 3.14 × 9² × 10
Volume = 1/3 × 3.14 × 81 × 10
Volume = 847.8 ft³
