Question

Tolong dijawab yaaa
please soalnya besok saya les jadi ini harus selesai besok

Answer 1

28. V tabung = π × r² × t
= 3,14 × 10² cm × 40 cm
= 3,14 × 100 cm × 40 cm
= 314 × 40 cm
= 12.560 cm³

29. V1 kubus = s³
= 8³ cm
= 512 cm³

v2 balok = p × l × t
= 20 cm × 8 cm × 9 cm
= 1440 cm³

v = v1 + v2
= 512 cm³ + 1440 cm³
= 1952 cm³

insya allah semua bener
