Answer:
The answer to your question is: human hair is 30 times greater than spider silk.
Step-by-step explanation:
Data
Diameter human hair = 9 x 10 ⁻⁵ m
Diameter of spider silk = 3 x 10⁻⁶ m
Process
times = 9 x 10⁻⁵ / 3 x 10 ⁻⁶
times = 30
Answer:
![\displaystyle V\approx 769.7\text{ in}^3](https://tex.z-dn.net/?f=%5Cdisplaystyle%20V%5Capprox%20769.7%5Ctext%7B%20in%7D%5E3)
Step-by-step explanation:
We are given that the diameter of the sand-shaped cone is 14 inches, and the height is 15 inches.
The volume for a cone is given by:
![\displaystyle V=\frac{1}{3}\pi r^2h](https://tex.z-dn.net/?f=%5Cdisplaystyle%20V%3D%5Cfrac%7B1%7D%7B3%7D%5Cpi%20r%5E2h)
Where r is the radius and h is the height.
Since the diameter is 14, the radius is 7.
And we are given that the height is 15.
Therefore, the volume will be:
![\displaystyle V=\frac{1}{3}\pi (7)^2(15)](https://tex.z-dn.net/?f=%5Cdisplaystyle%20V%3D%5Cfrac%7B1%7D%7B3%7D%5Cpi%20%287%29%5E2%2815%29)
Use a calculator:
![\displaystyle V\approx 769.7\text{ in}^3](https://tex.z-dn.net/?f=%5Cdisplaystyle%20V%5Capprox%20769.7%5Ctext%7B%20in%7D%5E3)
The volume of the cone is approximately 769.7 cubic inches.
