tinggi kerucut = t = 12 cm
garis pelukis kerucut = s = 15 cm
jari-jari tabung = jari jari alas kerucut = r
r² = s² - t²
r² = 15² - 12²
r² = 225 - 144
r =√ 81 = 9
r = 9 cm

tinggi tabung = 30 cm
jarijari alas tabung = 9 cm
volume tabung = πr²t
= π × 9² × 30
= π × 81 ×30
= π 2430
volume tabung = 2.430 π cm³
