A cone fits inside a square pyramid as shown. For every cross section the ratio of the area of the circle to the area of the square is pi r^2 / 4r^2 or pi/4. Since the area of the circle is pi/4 the area of the square , the volume of the cone equals what?

Identify the function that contains the data in the following table: x     -2         0         2         3         5     f(x)     5         3         1         2         4     possible answers: f(x) = |x| + 1 f(x) = |x - 2| f(x) = |x - 2| - 1 f(x) = |x - 2| + 1
