In the Changing Dimensions of 3D Figures
section, if a prisms dimensions were
changed by a scale factor of 3, how would
the surface area change?*
O
It would stay the same
O
It would change by a scale factor of 3.
It would change by a scale factor of 6.
O
It would change by a scale factor of 9.
O
It would change by a scale factor of 27.

factor of 9

Step-by-step explanation:

Given

prism were changed by a scale factor of 3

Suppose prism is rectangular in shape

So surface are is

Where l=length

w=width

b=breadth

So new length,breadth and width is

So new surface area would change by a factor of 9

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)
