Rl - rubber layer, s - sphere, b - ball

V_{rl}=V_b-V_s\\
V=\dfrac{4}{3}\pi R^3\\\\\\
V_{rl}=\dfrac{4}{3}\cdot3.14\cdot22^3-\dfrac{4}{3}\cdot3.14\cdot18^3\\
V_{rl}=\dfrac{4}{3}\cdot3.14(10648-5832)\\
V_{rl}=\dfrac{4}{3}\cdot3.14\cdot4816\\
V_{rl}=20162.99\text { in}^3

Answer:

< 4, - 7 >

Step-by-step explanation:

- w - z

= - < - 5, 3 > - < 1, 4 > ← multiply each component in w by - 1

The formula for volume always involves three dimensions.  

In this case, the volume of a cube is V=s^3, where s is the side length of the cube.

To solve for that side length, you'd need to use a cube root.
