Answer:

105.57 cubic feet.

Explanation:

A delivery truck arrived in the construction site and pouring a cone-shaped pile of gravel 6 feet high with a diameter at the base of 8.2 feet.

Therefore, the volume of the cone shaped pile is
(1)/(3)\pi  r^(2)h, where r =
(8.2)/(2)=4.1 feet and h = 6 feet.

Hence, V =
(3.14 *(4.1)^(2)* 6 )/(3) =105.57 cubic feet.

So, 105.57 cubic feet of gravel was delivered. (Answer)
