Luas:

Lp = 2πr(r+t)

Lp = 2 × 22/7 × 28 × (28 + 20)

Lp = 2 × 22/7 × 28 × 48

Lp = 2 × 22 × 28 × 48/7

Lp = 59.136/7

Lp = 8.448 cm²

Volume:

V = πr²t

V = 22/7 × 28² × 20

V = 22/7 × 784 × 20

V = 22 × 784 × 20/7

V = 344.960/7

V = 49.280 cm³

d = 20

r = d/2

r = 20/2

r = 10 cm

V = πr²t

V = 3,14 × 10² × 50

V = 3,14 × 100 × 50

V = 314 × 50

V = 15.700 cm³

V = 15,7 liter

Penjelasan dengan langkah-langkah:

1. Diketahui r = 28 dan t = 20

Volume tabung = π × r² × t

= 22/7 × 28 × 28 × 20

= 49.280 cm³

Luas tabung = 2πr(r + t)

= 2 × 3.14 × 28(28 + 20)

= 175,84 × 48

= 8.440,32

2. Diameter = 10 + 10

Volume tabung = π × r² × t

= 3,14 × 10 × 10 × 50

= 15.700 cm³

Liter = 1000cm³

15.700 cm³ ÷ 1.000

= 15,7 liter

Maaf kalau salah

Jadikan yg terbaik plss
