Verified answer
R = 4 cm = 40 mmt = 9 cm = 90 mm
Volume 4 Kaleng Susu
= 4 x Πr²t
= 4 x 3,14 x 40 x 40 x 90
= 4 x 3,14 x 144,000
= 4 x 452,160
= 1,808,640 mm³
V.Tabung = phi x r² x t
Diketahui:
r/jari-jari = 4cm
tinggi = 9cm
Ditanyakan :
Berapa mm³ susu yg dibeli?
Penyelesaian:
V = phi x r x r x t
= 3,14 x 4 x 4 x 9
= 3,14 x 16 x 9
= 3,14 x 144
= 452,16cm³
Dikali 4 karena ada 4 kaleng
= 452,16 x 4
= 1.808,64cm³
Diubah ke mm³
= 1.808,64 x 1000
= 1.808.640mm³
semoga membantu!
