Penyeesaian dik : v = 46,2 liter = 46,2 dm^3 = 46200 t. = 75 cm π = 22/7 ditanya : d = ......? jawab : v = 2πrt 46200 = 2 x 22/7 x r x 75 46200 = 44/7 x r x 75 46200 x 7 = 44 x r x 75 323400 : 75 = 44 x r 4312 : 44 = r 98 = r. d = r x 2 = 98 x 2 = 196 jadi, diameter tabung tsb adalah 196 cm
dik : v = 46,2 liter
= 46,2 dm^3
= 46200
t. = 75 cm
π = 22/7
ditanya : d = ......?
jawab : v = 2πrt
46200 = 2 x 22/7 x r x 75
46200 = 44/7 x r x 75
46200 x 7 = 44 x r x 75
323400 : 75 = 44 x r
4312 : 44 = r
98 = r.
d = r x 2
= 98 x 2
= 196
jadi, diameter tabung tsb adalah 196 cm
