1sampai3 pakai cara pleaseee besok di kumpulin thanks yg udah bantu

1. volume = PxR²xT
p = 22/7
d = 14
r = 7
v= 1540

1540 = 22/7 x 7 x 7 x t
1540 = 154 x t
t = 10cm

2. volume = p x l x t
p = 2+l
720cm³ = luas alas x t
720cm³ = 120 x t
t = 6cm

720cm = 6 x p x l
720 : 6 = p x l
120 = p x l
*lalu cari p&l , dgn syrt PxL = 120 dan P lebih besar 2cm*

p = 12
l = 10cm
