tolong di bantu ya pakai cara dari no 26,27,28,29,30 pakai cara

26. bangun 1 + bangun 2= (14+14+14+14)+(14+14)= 84
27. balok
28. 6 x 18 x 18= 1944
29. seperempat x phi x diameter 2 x tinggi= 28.260 cm kuadrat
30. bangun 1 +bngun 2 = (16 x 16 x 16)+(seper2 x a x t x t.prisma)
                                      = 4096+1280= 5376
      

26. kk=14 × 4
=56 cm
kl =22/7 × 28
=88 × 1/4
=22 cm
=56 + 22
=78 cm ( C )

27. A. Balok

28. LP = 6 × S × S
= 6 × 18 × 18
= 1.944 cm ( D )

Sorry no 29 gk bsa

30. Vk = 16 × 16 × 16
= 4.096
Vp = 16 × 10 × 1/2
= 160 × 1/2
= 80 × 16
= 1.280 cm
= 4.096 + 1.280
= 5.376 cm ( B )

maaf klo salah
