What is the outside diameter of a tubing whose inside diameter is 2 3/16 inch. And whose wall thickness is 3/8 in

Outside diameter = 3 3/16 + 3/8 + 3/8

                           = 3 3/16 + 12/16 = 3 15/16"

Step-by-step explanation:

81 seats

step-by-step explanation:

if you multiply 0.65 times 125 then you get 81.5 seats. well since you can't have half of a seat you have to round down and get 81 seats in the no children zones. that leave 44 seats outside of the no children zone.
