kwak bantu dwong poinnya mayan lohhh, pakek cara yaa
Penjelasan dengan langkah-langkah:
26) Lp = 4πr²
r² = 5.544/(4 x 22/7)
r² = 5.544/88 x 7
r² = 63 x 7
r² = 441
r = √441
r = 21 cm
27) Volume = p x l x t
= 9 × 5 × 6
= 45 × 6
= 270 cm³
28) Lp = πd(r + t)
= 3,14 x 20 x (10 + 16)
= 62,8 x 26
= 1.632,8 cm²
29) Lp A = 2(9x5 + 9x6 + 5x6)
= 2(45+54+30)
= 258 cm²
Lp B = 2(10x5 + 10x4 + 5x4)
= 2(50+40+20)
= 220 cm²
Selisih A dan B = 258 - 220 = 38 cm²
