kak tolong banget bantuin soal mtk untuk ujian besok. dengan penjelasan&rumus​

Answer 1

Jawab:

Penjelasan dengan langkah-langkah:

1. BOC dan COD

2. K.O = 2[tex]\pi[/tex]r

= 2 x 22/7 x 28

= 44/7 x 28

= 1.232/7

= 176cm^2

3. L.O = [tex]\pi[/tex]r^2

= 3,14(16)^2

= 3,14 x 256

= 803.84cm^2

4. volume kubus = s^3

= 6^3 (6 x 6 x 6)

= 216cm^2

5. luas permukaan = 6 x (s x s)

= 6 x (8 x 8)

= 6 x 64

= 384

6. Luas segitiga = 1/2 x a x t

= 1/2 x 9 x 6

= 1/2 x 54

= 27

7. Luas Limas = Luas Alas x Luas Selubung

Luas Alas = s x s

= 8 x 8

= 64

Luas Selubung = 1/2 x a x t

= 1/2 x 12 x 8

= 1/2 x 92

= 48

Luas limas = L.Alas x L.Selubung

= 64 x 48

= 3.072cm^2

8. Modus = data paling banyak = 12

Median = nilai tengah = 12.5

9. mean = rata rata = (6 + 3 + 2 + 4 + 3 + 4 + 2 + 4 + 1 + 7) : 10

= 3.6

10. frekuensi = 24/50

= 12/25

semoga membantu yakkkk
