5. Diketahui =

• v. kaleng (v. tabung) = 1.540 cm²
• r. kaleng = 7 cm
• π = 22/7

v = π × r² × t

1.540 = 22/7 × 7² × t

1.540 = 22/7 × 49 × t

1.540 = 22 × 7 × t

1.540 = 154 × t

t = 1.540 : 154

t = 10 cm

6. Diketahui =

• l. alas = 176 cm²
• t = 18 cm
• π = 22/7

v = 1/3 × l.alas × t

v = 1/3 × 176 × 18

v = 176 × 6

v = 1.056 cm³

7. Diketahui =

• v = 4.620 cm³
• r = 21 cm
• π = 22/7

v = 1/3 × π × r² × t

4.620 = 1/3 × 22/7 × 21² × t

4.620 = 1/3 × 22/7 × 441 × t

4.620 = 1/3 × 22 × 63 × t

4.620 = 22 × 21 × t

4.620 = 462 × t

t = 4.620 : 462

t = 10 cm

8. Diketahui

• l. alas = 90 cm²
• v = 300 cm³

v = 1/3 × l. alas × t

300 = 1/3 × 90 × t

300 = 30 × t

t = 300 : 30

t = 10 cm

9. Diketahui =
