Answer 1

• V tabung = π × r² × t
• V tabung = 22/7 × 21 × 21 × 15
• V tabung = 22 × 3 × 21 × 15
• V tabung = 66 × 315
• V tabung = 20.790 cm³

Answer 2

Diket: r = 21 cm

t = 15 cm

Ditanya: Volume?

Jawab:

v = π × r × r × t

= 22/7 × 21 cm × 21 cm × 15 cm

= 22 × 3 cm × 21 cm × 15 cm

= 66 cm × 21 cm × 15 cm

= 1.386 cm² × 15 cm

= 20.790 cm³
