tolong bantu dari delapan sampai 14

Latihan ulangan umum semester 1
Nomor 8 - 14

8 . 50 dm3 / detik = ... cm3 / detik
= 50 × 1000 = C) 5000

9 . gak ada jawabannya

10. 25 × ( 40 - n ) = ( 25 × 40 ) - ( 25 × 32 )
; n = A) 32

11 . 84 = 2^2 × 3 × 7
98 = 2 × 7
FPB = 2 × 7 = C) 14

12 . 3√ 512 + 3√ 1000
= 8 + 10 = B) 18

13 .
Dik = Tinggi segitiga = 16 cm
= Alas segitiga = 12 cm
= Tinggi prisma. = 42 cm
La. = 1/2 × 16 × 12
= 1/2 × 182 cm2 = 96 cm2
Volume = La × Tinggi
= 96 cm2 × 42 cm = B) 4032

14 . 4000 dm3 / detik = ... m3 / menit
= 4000 × 60 : 1000 = A) 240

Bonus : nomor 15 - 16

15 . Dik = R ( radius ) = 14 cm
= T ( tinggi ) = 28 cm
= π = 22/7
La = 22/7 × 14 cm × 14 cm = 616 cm2
Volume = Luas alas × Tinggi
= 616 cm2 × 28 cm = A) 17248

16 . 50 m3 / menit = ... dm3 / menit
= 50 × 1000 = C) 50000

*Semoga membantu n maaf klo salah
