1. Sebuahtabungberisi 770 cm³ zatcair, panjangjari-jari alas tabung 7 cm. Hitung ! A. Tinggizatcair ? B. Luaspermukaantabung ?

### Jawaban :

Diketahui : b. L. Permukaannya :

V = 770 cm³ » 2 π r (r+t)

r = 7 cm » 2 . 3,14 . 7 . 12

Ditanya : t = . . . ? » 2 . 264

» 528 cm²

V = π r² t Jadi, luaspermukaantabungtersebut

770 = 3,14 x 7x 7 x t ialah 528 cm².

770 = 3,14 x 49 x t

t = 770 : 154

t = 5 cm
