Jawaban:

Volume tabung :

V = πr² x t

V = 3,14 x (8cm)² x 20cm

V = 3,14 x 64cm² x 20cm

V = 3,14 x 1280cm³

V = 4019,2 cm³

volume kerucut :

V = ⅓ πr² x t

V = ⅓ 3,14 x (8cm)² x 20cm

V = ⅓ 3,14 x 64cm² x 20cm

V = ⅓ 3,14 x 1280cm³

V = ⅓ 4019,2 cm³

V = 1339,73 cm³

volume gabungan :

V tabung + V kerucut

= 4019,2 cm³ + 1339,73 cm³

= 5358,93 cm³
