Which of the following integrals correctly computes the volume formed when the region bounded by the curves x^2 + y2 = 25, x = 3, and y = 0 is rotated around the y-axis?

Which of the following integrals correctly computes the volume formed when the region bounded by the curves x2 + y2 = 25, x = 3, and y = 0 is rotated around the y-axis?

Question options:

1) pi times the integral from 0 to 4 of the square of the difference between the square root of the quantity 25 minus y squared and 3, dy

2)  pi times the integral from 0 to 4 of the square of the square root of the quantity 25 minus y squared minus 3 squared, dy

3)  pi times the integral from 0 to 4 of 3 squared minus the square of the square root of the quantity 25 minus y squared, dy

4)  pi times the integral from 3 to 5 of the square of the square root of the quantity 25 minus x squared, dx
