6. gambar tidak jelas
7. Lp. kubus = 6 × r²
1.944 cm² = 6 × r²
r² = 1.944 : 6
r² = 324
r = √324 = 18 cm (D)
8. Lp. tabung = 2 × π × r (r + t)
= 2 × 22/7 × 7 (7 + 12)
= 2 × 22 × 19
= 836 cm² (A)
9. gambar kurang jelas
jika nomer 6 dan 9 mau saya jawabkan , tolong fotokan soal dengan jelas terlebih dahulu yaa...
semoga membantu
