Question

Guengle works in urban landscape design a truck arrived pouring a cone shaped pile of gravel six feet high with a diameter at the base of 8.2 ft how much gravel was delivered use pie\

Answer 1

`105.56\ ft^3` of gravel was used.

Explanation:

Given that,

The height of a cone, h = 6 feet

The diameter of the base of cone, d = 8.2 feet

Radius, r = 4.1 feet

We need to find the amount of gravel was delivered. The volume of a cone is given by :

`V=(1)/(3)\pi r^2 h\\\\=(1)/(3)* 3.14* 4.1^2* 6\\\\V=105.56\ ft^3`

So,
`105.56\ ft^3` of gravel was used.
