kemasan minuman berbentuk tabunt dengan keliling alas = 22 cm dan tinggi 10 cm. tentukan volume kemasan

klling alas = 22/7.d
d = 7/22.22
d= 7 cm
r = 3,5 cm
luas alas = 22/7.3,5.3,5 = 38,5 cm2
volume tabung = 38,5 x 10 = 385 cm2


good luck... foloow.. be a the best

K.alas = 2πr
22 = 2x22/7xr
22= 44/7xr
22x7 =44r
154 = 44r
r = 3.5cm
V. Tabung = πxr^2xt= 22/7 x 3.5^2 x 10
= "385"
