Padat terdiri dari kerucut dan silinder. Jari-jari silinder adalah 7 cm. Jika tinggi silinder 10 cm dan tinggi padatannya 16 cm, maka volume padatannya adalah ... cm
r = 7 cm
t tabung = 10 cm
tinggi kerucut = 16-10 = 6 cm
volumenya adalah
= volume tabung + volume kerucut
= phi r^2 t + 1/3 phi r^2 t
= 22/7 x 7 x 7 x 10 + 1/3 x 22/7 x 7 x 7 x 6
= 1540 + 308
= 1840 cm^3
