A grain silo consists of a cylindrical main section and a hemispherical roof. If the total volume of the silo (including the part inside the roof section) is 11,000 ft3 and the cylindrical part is 30 ft tall, what is the radius of the silo, correct to the nearest tenth of a foot?
r =  ft

The real solutions of the given equation are rational. List all possible rational roots using the Rational Zeros Theorem. (Enter your answers as a comma-separated list.)

x3 − 3x2 − 4x + 12 = 0;  [−4, 4] by [−15, 15]

List all possible rational zeros given by the Rational Zeros Theorem (but don't check to see which actually are zeros). (Enter your answers as a comma-separated list.) I tried -1.5,\ 2.08,\ 5.42

P(x) = x3 − 6x2 + 17

All the real zeros of the given polynomial are integers. Find the zeros. (Enter your answers as a comma-separated list. Enter all answers including repetitions.) I tried 3

P(x) = x3 − 9x2 + 27x − 27

Thank you.
