Jawaban:
V besar = 18.480 cm³
t besar = 30 cm
V besar = phi × R × R × t besar
18.480 = 22/7 × R × R × 30
R × R = 18.480 ÷ 30 ÷ 22/7
= 616 × 7/22 = 28 × 7 = 196
R = akar 196 = 14 cm
Pd gambar, terlihat, jari2 tabung besar sama dengan diameter tabung kecil.
R = d
14 = 2 r
r = 14 ÷ 2 = 7 cm
Jd jari2 tabung kecil = 7
Tinggi tabung kecil = 30 cm
V tabung kecil = phi × r × r × t
= 22/ 7 × 7 × 7 × 30
= 22 × 7 × 30
= 4.620 cm³
