Find the volume of this cylinder. Use 3 for 1. 2 in
V = arah

12 in
V
V~ [?]in3

  36 in³

Step-by-step explanation:

The formula for the volume of the cylinder uses r to represent the radius, and h to represent the height. The figure shows the diameter to be 2 inches. The radius is half that, or 1 inch. The figure shows the height to be 12 inches.

Using the given numbers in the formula, you find the volume to be ...

  V = πr²h

  V = (3)(1 in)²(12 in) = 36 in³

answer: a parabola

steps:

(x-1)(x+4)   = x(x+4) - 1(x+4) = (x^2 + 4x) - (x+4)

                = x^2 +4x -x -4   = x^2 +3x -4

which is a parabola
