Answer:

Step-by-step explanation:
Given

Required
Find 
First, we calculate the inverse function

Express f(x) as y

Swap the positions of x and y

Solve for y: Add 4 to both sides


Square both sides

Divide both sides by 2

Express y as an inverse function

Next, solve for: 
Substitute 6 for x




1 ) V = 1/3 * 18² * 3.14 * 6 = 2,034.72 mm³
2 ) V = 1/3 * 6² * 3.14 * 9 = 339.12 in³
3 ) V = 1/3 * 150² * 3.14 * 240 = 5,652,000 in³
5,652,000 : 12,000 = 471 weeks
