Volume sebuah tabung 1.848 dm dan tinggi nya 12 dm. Berapa dm jari jari tabung tersebut?

t = 12dm

V. tabung = πr²t
1848 = 22/7×r²×12
1848×7 = 264r²
12936 = 264r²
r² = 12936/264
r² = 49
r = √49
r = 7

jadi jari jari = 7dm

semoga membantu

volum tabung = [tex] \pi [/tex] x r² x t
1848               = 22/7 x r² x 12
1848               = 264/7 x r²
r²                     = 1848 :   264/7
r²                     = 1848 x 7/264
r²                     = 12.936 / 264
r²                      = 49
r                        =√49
r                        = 7 dm
