  • tinggi = t = 10cm
    jarijari=r= 7cm
    phi= 22/7
    volume kerucut = 1/3 × phi× r^2×t
    = 1 /3 × 22/7 × 7 ×7 × 10
    = 1/3 × 22 × 7 ×10
    = 1/3 × 1540
    = 513, 3 cm^3
    volume kerucut ÷ 4 = bagian yang hilang = 513, 3 ÷ 4 = 128, 325 cm^3 = 128, 3 cm^3
    volume kerucut sisanya 513, 3 - 128, 325 = 384, 975 = 385 cm^3
