Answer 1

13) volume tabung = π×r²×t
= 22/7 × 14 × 14 ×20
= 22 × 2 × 14 × 20
= 12.320

volume balok = p × l × t
= 28 × 28 × 20
= 15.680

volume gabungan = 12.320 + 15.680
= 28.000

15) volume kubus = p × l × t
= 7 dm × 6 dm × 5 dm
= 210 dm³

volume tabung = π × r² × t
= 3,14 × 1,75 × 1,75
= 3,14 × 3,0625 × 3
= 238.665

volume gabungan = 210 + 238.665
= 238.875
