Determine if the graph is symmetric about the x-axis, the y-axis, or the origin. r = 4 cos 3θ
i don't think it's symmetric?

                The graph is symmetric about the x-axis.

Here we have equation as:

(  Since, we know that:

 )

Hence, the graph is symmetric about the x-axis.

Hence, we observe that on replacing the function the two graphs are not equivalent.

Hence, the graph is not symmetric about the y-axis.

Hence, we observe that on replacing the function the two graphs are not equivalent.

Hence, the graph is not symmetric about the pole(origin)

518,400

step-by-step explanation:

the area is multiplying all the given measurements together.

40 * 18 * 30 * 24 = 518,400
