Question

C. hitunglah luas permukaan dan volume dari bangun tabung diatas!​

Answer 1

• r = 4 cm
• t = 12 cm

• Luas Permukaan:

Lp = 2πr(r+t)

Lp = 2 × 3,14 × 4 × (4 + 12)

Lp = 25,12 × 16

Lp = 401,92 cm²

• Volume:

V = πr²t

V = 3,14 × 4² × 12

V = 3,14 × 16 × 12

V = 50,24 × 12

V = 602,88 cm³
