Find the volume of the grain when the height of the pile is ten feet and the radius of the base is
feet. Use appropriate precision on your results.
As the pile grows, the cones formed remain similar. If the radius of the base is four feet when the height is ten feet, what is the radius of the base when the height is
Write a proportional equation and solve for the unknown value.
Consider the angle the side of the cone-shaped pile makes with the ground. Is this angle changing? Justify your answer. If not, what is the measure of the angle?
What trig function would help you find the angle?
