Answer:
The scale factor is 1/6.
Step-by-step explanation:
the larger triangle is 6 times larger than the small triangle because 24 divided by 4 is 6, so therefore the scale factor of the big triangle to the small triangle is 1/6.
k = 4/24 = 1/6
72 pi + 48 pi= 120pi (not sure if I am right tho)
the answer is 32.........
