Tolong jawabanya
terima kasih

Answer 1

4. lk = 24, tk = 36, lf = 24-6 = 18, tf = 33-x
lk/lf = tk/tf
24/18 = 36/33-x
4/3 = 36/33-x
132-4x=108
-4x = 108-132
-4x = -24
x = 6 (lebar bagian bawah karton)

5. d sb = d pp . s
= 4cm . 200 = 800 cm = 8m
r = 1/2 d = 1/2 . 8m = 4m
L = phi . r . r
= 3,14 . 4m . 4m = 50,24 m^2

maaf nomor yang lainnya ga bisa ._.
