Question 156147
I think they threw in the fact that the swan "is 4 ft. long" to throw you off (since it's extra info that you don't need)


{{{L=2.43*W^0.3326}}} Start with the given equation



{{{L=2.43*25^0.3326}}} Plug in {{{W=25}}}



{{{L=2.43*2.917}}} Raise 25 to the 0.3326th power to get 2.917



{{{L=7.08831}}} Multiply 2.43 and 2.917 to get 7.08831



So the approximate wingspan (we introduced rounding errors) is about 7.09 feet (rounded to the nearest hundredth).
