a circular plate has radius 15cm. every dimension is multiplied by 4 to create a larger, similar plate. how is the ratio of the circumferences related to the ratio of the corresponding dimesions? what is the ratio to the circumferences?(hint: think of circumference as perimeter if a circle.)

  • math -

    All linear dimensions, including the circumference, are multiplied by 4 in the larger plate.

    The area is 16 times larger.
