tolong di jawab pakai cara

volume tabung=1/4×phi×d×d×t
1/4×3,14×10×10×35
1/4×3,14×3500
1/4×11.090
=2.772,5
keliling kubus=12×29
=348 cm
luas kubus=sxs
29×29
841 cm
#maaf kalo luas alas nya gak dikerjain soalnya gak tau caranya

4.Luas = phi × r2
= 3.14×5pangkat2
= 3.14×25
= 78.5
vol = L alas×t
= 78.5×35
= 2747.5

5.K = 4×29
= 116

L = 29×29
= 841
