Answer:
25:52 the ratio of the area of one of these spheres to the area of the original sphere.
Explanation:
Radius of metal sphere ,R= 9
Volume of metallic sphere, V = 
Radius of small metal sphere = r
Volume of small sphere made form metal sphere = v
Volume of metallic sphere = Total volume of all 3 small spheres
V = 3v
![R=\sqrt[3]{3}r](https://tex.z-dn.net/?f=R%3D%5Csqrt%5B3%5D%7B3%7Dr)
Area of sphere = 
Area of metal sphere = 
Area of small metal sphere = 
The ratio of the area of small spheres to the area of the original sphere:
![=\frac{r^2}{(\sqrt[3]{3}r)^2}=\frac{1}{(\sqrt[3]{3})^2}=\frac{1}{2.08}=\frac{25}{52}](https://tex.z-dn.net/?f=%3D%5Cfrac%7Br%5E2%7D%7B%28%5Csqrt%5B3%5D%7B3%7Dr%29%5E2%7D%3D%5Cfrac%7B1%7D%7B%28%5Csqrt%5B3%5D%7B3%7D%29%5E2%7D%3D%5Cfrac%7B1%7D%7B2.08%7D%3D%5Cfrac%7B25%7D%7B52%7D)
25:52 the ratio of the area of one of these spheres to the area of the original sphere.
