Amound of gravel is shaped like a cone. circumference at the bottom is 250 feet. the pile is 35 feet high. how many cubic feet of gravel are in the pile. round 2 decimal places in each step and round the final answer to the nearest cubic foot

The answer is:  58058 cubic feet.

It is given that:

A mound of gravel is shaped like a cone. Circumference at the bottom is 250 feet.

This means that the circumference of the circle is: 250 feet

i.e. if r is the radius of the bottom of the cone then

Now, on rounding to 2 decimal places we have:

Also, the height(h) of the cone is given as:

The volume(V) of cone is given by:

which to the nearest foot is given by:

i believe the answer is d.

hope it you! : d
