What is the value of x for the similar shapes :( someone pls help I’ll give brainiest if u tell me how to do this

24 explanation: it said similar and I referred it to being the same just a half smaller, then I saw that 6 on the small square is like the 12 on the big square s If you see it you can do 6=12(half) and so then 12=24 (whole) on the big square:) hope this helped:)

the answer would be c ≈ 18.852*3.14= 6.286.28*3=18.85
