A quality control engineer writes an algorithm to determine whether a solid conical component is within acceptable manufacturing tolerances.

The volume of the cone, VVV, is calculated using its radius r r\,r and height hhh.

If the volume is strictly between 15 and 45, "Pass" is output.

Otherwise, "Fail" is output.

01 r = input("Enter radius")
02 h = input("Enter height")
03 V = (1/3) * 3.14159 * r * h
04 if V > 15 then
05     print("Pass")
06 else
07     print("Fail")
08 endif

The algorithm does not work correctly.

Identify the line number of the two logic errors in the algorithm and write the corrected code for each line.
