A pile of sand is in the shape of a cone. The diameter of the sand pile is 18 ft and the height is 10 ft. What is the volume?

Step-by-step 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
