If it is scaled by a factor of 1.5. Your new values would be 18 inches lengthwise. And 8.55 for the diameter. So next you would fill these values into the formula for finding the volume of a cone. V=3.14 (r) ^2 (h/3) Radius is half diameter so 8.55/2 = 4.275. So the completed formula would be pi (4.275) ^2 (18/3). Simplified to pi (4.275) ^2 (6).

In the end. The volume would be about 344.49. in^3
