Ada yang bisa jelaskan gk tolong dong....

1) Ls = 4400 cm"
La = π.r" = 22/7.35.35 = 3850
L = Ls + La = 4400 + 3850 =8250

2) diket V = 88 ltr = 88.000 cm'''
t = 70 cm, ditanya r.....?
V = πr''t = 22/7.r''.70 = 88.000
220.r'' = 88.000
r'' = 88.000/220 = 400
r = √400 = 20

smg mmbantu jangan lupa folow kaka ya....:)
