Answer:
Hence the volume of the cone is 31384.52 cubic feet
Step-by-step explanation:
We must first need to understand how the volume of a cone is calculated.
It is simply calculated by multiplying the base area of the cone by the height, and dividing the result by 3.
This is :
Volume of cone = 
we are not given the base area of the cone. However, we are given the circumference from which we can get the radius of the base.
Circumference =

hence the volume of the cone is

Hence the volume of the cone is 31384.52 cubic feet
Answer:
Yes
Step-by-step explanation:
Because it’s a trapezoid and those can be trapezoid because they have one pair of parallel sides and a parallelogram has two pairs of parallel sides so a parallelogram is also a trapezoid.
Volume of bottom figure = 9 * 4 * 8.5 = 306 cubic centimeters
Volume of top figure = .5 * 1.5 * 2 * 4 = 6 cubic centimeters
TOTAL volume = 312 cc
