In a circle with a radius of 8 ft, an arc is intercepted by a central angle of 3π4 radians.
sineoko [7]
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
