"the cross- sectional area of a circular duct is 226.865 square inches. what would be the diameter of the duct"

______________________________________

A= pi(r^2) = 226.865 in^2

r= sqrt [ 226.865/ pi ]

r = 8.497845

d = 2r

= 17

the diameter is 17 inches

Right. I get 17 inches also.

ok thanks
