tolong jawab dong ya pliss.skrg

1. V = p x l x t
= 3 × 2 × 1 = 6 dm3

W = v : debit
= 6 : (1000 cc:1000) = 6 : 1 dm3
= 6menit
= 08.58 + 6 = 09.04

2. L1 = p x l = 35 x 20 = 700cm2
r = d : 2 = 20 : 2 = 10
L2 = 1/2 x 3,14 x r2
= 1/2 x 3,14 x 10 x 10
= 1/2 x 314 = 157cm2
Ls = L1 + L2 = 700 + 157 = 857cm2


"maaf kalo salah"
