tolong ya kak No 6-10 sama caranya

6. Luas ¾ lingkaran = ¾ x 22/7 x 28 x 28
= 66 x 28 (coret-coret)
= 1.848cm² (B)

7. Luas segitiga = ½ x a x t
325 = ½ x 26 x t
325 = 13 x t (coret-coret)
325 : 13 = t
t = 25cm (D)

8. Volume tabung = π x r² x t
= 3,14 x 10 x 10 x 65
= 314 x 65
= 20.410cm³ (D)

9. Volume prisma segitiga = ½ x a x t x t prisma
= ½ x 24 x 15 x 38
= 12 x 15 x 38
= 6.840cm³ (C)

10.Luas segitiga = ½ x Luas jajar genjang
½ x a x t = ½ x 396
½ x 22 x t = 198
11 x t = 198
t = 198 : 11
t = 18cm (D)
