1540:10=154154=22:7×r2
49=r2
7=r
jadi jari2 nya =7 cm
Materi Luas dan Volume
Diketahui:
Volume Tabung = 1.540 cm³
Tinggi Tabung = 10 cm
Ditanya:
Jari-jari Tabung = ...?
Penyelesaian:
Volume Tabung = π . r² . t
1.540 = 22/7 . r² . 10
1.540 = 220/7 . r²
r² = 220/7 : 1.540
r² = 7/220 x 1.540 (1.540 : 220 = 7)
r² = 7 x 7
r² = 49
r = √49
r = 7 cm
Jawaban:
Jadi, jari-jari tabung tsb. = 7 cm
Semoga Membantu^-^
