Pertama koreksi dulu keliling alas dimensi nya cuma 1 jadi satuannya cm saja keliling alas 62,8 cm t= 12 cm v= la x t keliling krc = 62.8 cm 2 r = 62.8 cm r =62.8 /2 =62.8/62.8 =1 cm la= =3.14 =3.14 v= la x t =3.14 x 12cm =37.68
keliling alas 62,8 cm
t= 12 cm
v= la x t
keliling krc = 62.8 cm
2 r = 62.8 cm
r =62.8 /2
=62.8/62.8
=1 cm
la=
=3.14
=3.14
v= la x t
=3.14 x 12cm
=37.68
