In the supermarket there is a scale that measures the weight of fruit and vegtsbles. The nedle is 24 cm long and it roatated 96d

Galina-37 [17]

Answer:

The distance of needle cover as it rotate is 0.700688 cm

Step-by-step explanation:

Given as :

The length of the needle = r = 24 cm

The needle is rotated at angle = Ф = 96°

The distance of needle cover as it rotate = length of arc made = l cm

The radius of arc = length of needle = r cm

<u>Now, According to question</u>

The distance of needle cover as it rotate = $\dfrac{\Pi \times radius\times \Theta }{180^{\circ}}$

where , π = 3.14

Or, l = $\dfrac{\Pi \times r\times \Theta }{180^{\circ}}$

Or, I = $\dfrac{3.14 \times 24 cm\times 96^{\circ} }{180^{\circ}}$

Or, l = 75.36 × 0.533°

∵ 180° = 3.14 radian

So, 0.533° = 0.0092978

So, l = 75.36 × 0.0092978

∴ l = 0.700688 cm

So,The distance of needle cover as it rotate = l = 0.700688 cm

Hence, The distance of needle cover as it rotate is 0.700688 cm Answer
