Jerry Huang · Answer 1

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.
