Answer: 8.94
Step-by-step explanation:
Actually, there would be no solution because the w's cancel out so that leaves -6=-9 and that is not true.
To find the circumference of a circle you do:
C=2πr or C= 2(3.14)(1.5)
3.14 is Pi, and the 1.5 is because the diameter is 3ft and the radius is half of the diameter.
when you multiply 2•3.14•1.5 you will get an answer of 9.42.
