Can someone plz me understand what is the center of dilation

answer: figure a's scale factor: 2

                figure a's center of dilation: (0,0)

              figure b's scale factor: 1/2

              figure b's center of dilation: (3,2)

              figure c's scale factor: 3

              figure c's center of dilation: (0,2)

              figure d's scale factor: 2 1/2

              figure d's center of dilation: (3,0)

step-by-step explanation:

its 4 because 2 times 2 is 4, if you double the number two you get four

(a) the volume of the cone is 20/3 in3

hence, option a is correct.
