Good day kindly assist with the below question with full working and answer

1. Set up and evaluate a triple integral, in cylindrical coordinates, to show that the volume of a cone of radius a and height h is rash. 2. (a) Set up the integral from (1) in cartesian coordinates with integration order dzdydx. Do not evaluate the integral (it is difficult). (b) Evaluate the inner integral with respect to z. Explain why it is difficult to finish the integration in cartesian coordinates. (You are welcome to try to finish the integration if you are up to the challenge)
