**Answer: V≈268.08**

**Step-by-step explanation: Use the formula ((V/π)(3/4))1/3. The volume of a sphere is derived from the equation V = (4/3)πr3. Solving for the r variable in this equation gets ((V/π)(3/4))1/3 = r, meaning that the radius of a sphere is equal to the volume divided by π, times 3/4, all taken to the 1/3 power (or the cube root.)**

**Answer:**

<em>**f(x) is 5x³ and g(x) is x+1**</em>

**Step-by-step explanation:**

Given the composite function:

h(x) = f(g(x)) = 5(x + 1)³

The function and be splitted into 5x³ and x+1 where f(x) = 5x³ and g(x) = x+1

Check:

f(g(x)) = f(x+1)

Substitute x with x+1 inn f(x)

f(x+1) = 5(x+1)³

f(g(x)) = 5(x+1)³ (which gives the required function

<em>**Hence one possibility of f(x) is 5x³ and g(x) is x+1**</em>
