Question

In the supermarket, there is a scale that measures the weight of fruit and vegetables. The needle is 24 cm long and it rotated 96Á when Charlie placed four tomatoes on it. How far did the needle travel as it rotated?

Answer 1

64pi/5

Explanation:

Answer 2

We find the length of the arc followed by the needle. For this, we first need to convert the subtended angle to radians:
96/∅ = 180/π
∅ = 1.68 rad
S = r∅
S = 24 x 1.68
Distance covered by needle = 40.32 cm
