16. Luas bangun datar gab = L persegi panjang + L 1/2 lingkaran = (18 cm x 7 cm) + (1/2 x 22/7 x 7 cm x 7cm) =126 cm^2 + 77 cm^2 = 203 cm^2
17. volume tabung = L.alas x tinggi = (22/7 x 35 cm x 35 cm) x 40 cm = 3.850 cm^2 x 40 cm = 154.000 cm^3
18. volume prisma segitiga = Luas alas x tinggi = 32m^2 x 23 m = 736 m^3
