Diameter = 2 x 14 = 28 cm
1 liter = 1dm³
jadi
volume tabung = 46,2 × 1dm³
volume tabung = 46,2 dm³
jadikan dm³ ke cm³
1dm³ = 1000cm³
volume tabung = 46,2 × 1000cm³
volume tabung = 46200cm³
kemudian kita cari diameternya
volume tabung = πr²t
46200cm³ = 22 × r² × 75cm
7
46200cm³×7 = 22 × r² × 75cm
46200cm³x7 = 75cm × r²
22
2100cm³×7 = 75cm × r²
2100cm³×7 = r²
75cm
28cm²×7 = r²
196cm² = r²
r² = 196cm²
r = √196cm²
r = 14cm
diameter = 2r
diameter = 2(14cm)
diameter = 28cm
jadi diameter tabung adalah 28cm
