The needle of the scale in the bulk food section of a supermarket is 26 cm long. Find the distance the tip of the needle travels when it rotates 64 degrees.
..
When the tip of the needle completed one revolution or 360�.
it would have traveled 2π*26 which is equal to the circumference of the circle made by the tip of the needle.
At 64� the tip would have traveled a fraction of the circumference.
64/360*2π*26=29.04 cm
ans:
Distance tip of the needle travels when it rotates 64 degrees=29.04 cm
