K’l’m’n’ is a dilation image of klmn. the center of the dilation is the origin. a) is the dilation an enlargement or a reduction? b) what is the scale factor of the dilation?

A) A contraction

B) A scale factor of 1/2

Step-by-step explanation:

The pre-image is LMNK and the image is L'M'N'K' and because the image is smaller than the pre-image, it is a contraction.

For the scale factor, we know it has to be at least less than 1 because it is a contraction. Notice the pre-image points are always exactly in the middle of the pre-image point and the origin, so we can assume that the scale factor is 1/2.

Hope this helps.

Have a good day! :)

v = 1/3 a^2h

step-by-step explanation:

if the height is 57.7cm and the height of the slant edge is 18.2cm, then the volume is 1/3 a^2h.
