Jawaban:
4. 351,68 cm²
5. B. 386 cm²
6. A. 1176 m²
7. C. Rp.350.000,00
8. C. 4517,33 cm³
Penjelasan dengan langkah-langkah:
4. L = πr² + 2πrt
= 3,14(16) + 2(3,14)(4)12)
= 50,24 + 301,44
= 351,68 cm²
5. L = 2(28) + 2(4+7)(15)
= 56 + 2(11)(15)
= 56 + 330
= 386 cm²
6. v = r³
2744 = r³
14 = r
L = 6r²
L = (6)14²
L = (6)196
L = 1176 m²
7. 25 × 14000 = Rp.350.000,00
8. v = 4/3πr³ + πr²t
= 4/3(22/7)(343) + 22/7(49)(20)
= 1437,33 + 3080
= 4517,33 cm³
