tolong dijawab y kk sebisanya kk aja mau no brp soalnya besok dikumpulin:)

1) V = 22/7 x 7x 7 x 5
= A. 770 cm3

2) V = 75 x 60 x 50
= 225000 cm3
= C. 225 liter

3) 6 (7,5) = 45
5 (8,5) = 42,5
4 (9) = 36
3 (5,5) = 16,5
2 (6,5) = 13
Total:
20. 153
Mean = 153/20
= B. 7,65

4) lebar = V/ (p x t)
= 60 : (4x5)
= 60 : 20
= A. 3cm

5) Berat setelah dijemur :
= 250,25 - (250,25 x 3/10)
= 250,25 -75,075
= A. 175,175 kw

6) 550.000/20
= B. 27500

7) r2 = L. lingkaran/phi
. = 1386 x 7 / 22
= 441
r = C. 21cm

8) L. P = 4 x 4 = 16 cm2
L. S = 1/2 x 4 x 3
= 6cm2
Total = 16 + 6
= 22 cm2

Tolong jadikan jawaban yg terbaik ya
