Did you mean 9×4? Because that is 36 and if you meant 9 to the power of 4 then that is 6,561
We know that
the length of a circumference=2*pi*r
for r=8 ft
the length of a circumference=2*pi*8---------> 16π ft
if 2π radians (full circle)-------------------> has a length of 16π ft
3π/4 radians-------------------------------> X
X=3π/4*16π/2π-------------> X=6π<span> ft
the answer is
6</span>π ft
