Best ResponseYou've already chosen the best response.0so the pipe has an outer diameter of 6 inches so radius 3 inches an inner diameter of 6 inches  2 x 1.25 so the inner diameter is 3.5 inches or radius 1.75 inches so find the area of the inner circle and then multiply by the height of 16 inches dw:1439237745793:dw
