jawaban no 14-15 ap sih

14. v. tabung kecil : pi * r * r * t = 22/7*5*5*7 = 550 cm'3 . v. tabung besar = 22/7*10*10*14 = 4.400 cm'3 . v. bangun ruang = 550+4.400= 4.950 cm'3

15. v. tabung : 22/7*1,75*1,75*3 = 28,875 dm'3
v. balok : p*l*t = 5*6*7 = 210 dm'3 . v. bangun ruang = 28,875+210 = 238,875 dm'3 = 238.875 cm'3
