Given that the diameter of a human hair ![= 9 \times 10^{-5}](https://tex.z-dn.net/?f=%20%3D%209%20%5Ctimes%2010%5E%7B-5%7D%20)
Given that the diameter of a spider's silk ![= 3 \times 10^{-6}](https://tex.z-dn.net/?f=%20%3D%203%20%5Ctimes%2010%5E%7B-6%7D%20)
Now we have to find how much greater is the diameter of a human hair than the diameter of a spider's silk.
To find that we just need to subtract the given numbers.
![9 \times 10^{-5} - 3 \times 10^{-6}](https://tex.z-dn.net/?f=%209%20%5Ctimes%2010%5E%7B-5%7D%20-%203%20%5Ctimes%2010%5E%7B-6%7D%20)
Since powers are not same so let's make them equal
![= 90 \times 10^{-6} - 3 \times 10^{-6}](https://tex.z-dn.net/?f=%20%3D%2090%20%5Ctimes%2010%5E%7B-6%7D%20-%203%20%5Ctimes%2010%5E%7B-6%7D%20)
now we can easily subtract the coefficients that is 3 from 9
![= (90-3) \times 10^{-6}](https://tex.z-dn.net/?f=%20%3D%20%2890-3%29%20%5Ctimes%2010%5E%7B-6%7D%20)
![= 87 \times 10^{-6}](https://tex.z-dn.net/?f=%20%3D%2087%20%5Ctimes%2010%5E%7B-6%7D%20)
![= 8.7 \times 10^{-5}](https://tex.z-dn.net/?f=%20%3D%208.7%20%5Ctimes%2010%5E%7B-5%7D%20)
Hence final answer is
.
The answer would be 48.85
Answer:
1017.36 mm²
Step-by-step explanation:
d = 2r => r = d/2 = 36mm/2 = 18 mm
A = π·r²
= 3.14×(18mm)²
= 3.14×324mm²
= 1017.36 mm²
