Let the region R be the area enclosed the function f(x)=x^3, the horizontal line y=6, and the y-axis. Find the volume of the solid generated when the region R is revolved about the line y=6. Round to the nearest thousandth. Please help! I have no idea how to do this!

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40

the correct answer is c
