In the supermarket, there is a scale that measures the weight of fruit and vegetables. The needle is 24 cm long, and it rotated 96° when Charlie placed four tomatoes on it. How far did the needle travel as it rotated?
The circular scale with radius (r)= 24 cm the central angle(C) = 96 deg Using the formula Arc length = 2pir(C/360) Arc length = 2 pi(24 cm)(96/360) Arc length = 64pi/5 The needle on the circular scale travelled 64pi/5 as it travel from the origin when Charlie placed four tomatoes on it.
