18.614 because a=πh(r^2)/3 pretty sure thats the formula but the answer is correct
The approximate diameter of the pile of sand in the cone that sand was dumped in is 9.30 feet.
A cone is a 3-dimensional object that consists of a ciruclar base and a vertex. The diameter is twice the length of the radius.
Radius = √[volume / (1/3 x π x height)]
√[136 / (1/3 x 22/7 x 6)]
√[136 / 6.29 = 4.65
Diameter = 4.65 x 2 = 9.30 feet
