What is the arc length of arc CD in the circle below? Circle A is shown with a radius labeled 8 feet and a central angle marked 35 degrees. 3.14 feet 4.88 feet 6.98 feet 11.78 feet
the length of the circumference (L)=2*pi*r r=8 ft so L=2*pi*8=16*pi ft the length of arc CD is 35°-------->let's transform the degrees to feet we apply a rule of three if 360° -----------------> 16*pi 35°---------------X X=35*16*pi/360--------> 4.88 ft
