The volume of the larger ball bearing is 8 times the volume of the
smaller one
Step-by-step explanation:
All the spheres are similar, and there is a ratio between their radii
So the ratio between their:
1. Diameters⇒ =
2. Areas ⇒ =
3. Volumes ⇒ =
∵ The radius of the larger ball bearing is twice the radius of the
smaller one
- That means the radius of the larger sphere is equal to the radius
of the smaller sphere multiplied by 2
∴ =
∵ =
∴ =
∴ =
<em>The volume of the larger ball bearing is 8 times the volume of the </em>
<em>smaller one</em>

C 12.5 hours it would take this long because it adds 3 more people and then you like do something and you subtract that Number by 20 and get 12.5 hours
The given diagram represents a cylinder, with radius = 8m and height =14m. To find the volume, we need to use the following formula
And on substituting the values of radius,r and height,h, we will get
Therefore the correct option is the last option .
