Sand is being dumped from a hopper railcar at a rate of 40 cubic feet per minute. It forms a pile in the shape of a right circular cone whose base diameter and height are always equal to each other (both are growing larger as more sand is dumped). How fast is the base diameter increasing when the base is 18 feet long? Round your answer to three decimal places. ft/min

Please answer the question in the attached file.  Please be as detailed as possible, as I don't understand the concept very well.

1. Determine the size of the matrix, if not possible, state why. Pay attention to multiplication verses addition when looking for the size! A4X2 – 3B4X2 a. b. A4x2 B2X12 C. B10x3 A10x3
