Finding the volume of circular cone.I´m trying to find the Volume of a Circular right cone. The height is 3 units (y-axis) and the radius is 2 units (x-axis).So, if i Want to find the volume I have to write a equation above in terms of "y", for this situation. Right? The question ask me the equation that generates the solid. I have found x = ( 2 / 3 ) y. Am I right?

Explanation:You can obtain geometrically the circular right cone by rotating the region bounded by the lines   y  =      2    3    x,   x  =  0 and   x  =  3. Using the formula for the volume of a solid of revolution, you must calculate   V  =      ∫          0              3        π            (              2        3            x      )        2    d  x which is pretty easy.
