A pentagon if it cut by a plane perpendicular to the base, the shape of the cross section is formed a rectangle.

Answer is C. a rectangle.

It depends.

If the prism is "right" with all faces perpendicular to the bases, the cross section will be C. a rectangle.

If one or more faces are not perpendicular to the base, the cross section could be any of the listed choices.

the circle graph is not a function.

step-by-step explanation:

the graph of the circle is not a function.

because for a graph to be a function, each value of x must give one value of y

in the circle, the values of x for -2< x< 2 each give 2 values of y.

hence this is not a function.
