Answer 1

4)volume =3388
tinggi = 22
r = ?

luas alas tabubg = volume/tinggi
= 3388/22
=154

diameter alas = √28 . luas /22
=√28 . 154 /22
=√4312/22
=√196
=14 cm

jafi jari alas = d/2
= 14/2
= 7 cm


5)p= 18
l=6
t=9
Lp = 2 (p.l + p.t +l.t)
=2 (18.6 +18.9+6.9)
=2 (108 +162+54)
=2 (324)
=648cm²

Answer 2

4. 3,388 ÷22 = 154
=154 ÷ π ( 22/7)
=7² (7 × 7 = 49)
5. Jawab = 2 × (18×6)+(18×9)+(6×9)
= 2 × (108+162+54)
= 2 × 324 = 648 cm²
Maaf kalo jawaban saya salah
