tolong di jawab ya bsk di kumpulkan

B.I = (22/7 * 14 * 14) + (22/7 * 28 * 14)
     = (22 * 2 * 14) + (22 * 4 * 14)
     = 616 + 1232
     = 1848
B.II = 2 * 22/7 * 14 * 14
      = 2 * 22 * 2 * 14
      = 1232
LUAS = B.I + B.II
          = 1848 + 1232
          = 3080
CAT = 3080/4 * 2
        = 770 * 2
        = 1540
INSYAALLAH BENAR
