Components 2565

The component is a regular decagon with a side of 2 cm. Its material weight of 1 m2 of sheet metal is 24 kg. What is the weight of 200 components?

Correct answer:

m =  14.7729 kg

Step-by-step explanation:

m=200⋅ 24⋅ (0.022⋅ 10/(4⋅ tan⁡(π/10)))=200⋅ 24⋅ (0.022⋅ 10/(4⋅ tan⁡(3.1416/10)))=14.7729 kgm = 200 \cdot \ 24 \cdot \ (0.02^{ 2 } \cdot \ 10/(4 \cdot \ \tan(\pi/10))) = 200 \cdot \ 24 \cdot \ (0.02^{ 2 } \cdot \ 10/(4 \cdot \ \tan(3.1416/10))) = 14.7729 \ \text{kg}
