Ted made a scale model of a submarine for his science class.

a. What is the volume of Tedâ€™s model?

b. If 1 inch in the model represents 20 feet in the actual submarine,

what is the volume of the actual submarine?

front round is 3 inch radius/length 3 inch

cylinder is length 12 inch

tail cone is 3 inch radius/length of 4 inches.

Need help with the secon part. Not sure is I explained it correctly the first time. I think I may have the first part incorrect.
