Answer 1

Jawab:

1. L = a × t
     = 10 cm × 14 cm
     = 140 [tex]cm^{2}[/tex]

2. L = 15 m × 2 m
      = 30 [tex]m^{2}[/tex]

3. L = 1/2 × d1 × d2
      = 1/2 × 20 cm × 30 cm
      = 300 [tex]cm^{2}[/tex]

4. L = 1/2 × a × t
      = 1/2 × 5 cm × 10 cm
      = 25 [tex]cm^{2}[/tex]

5. Segi empat / persegi = 90°
   Segitiga                      = 180°

6. Segienam

7. V = [tex]r^{3}[/tex]
   r = [tex]\sqrt[3]{V}[/tex]
   r = [tex]\sqrt[3]{64 cm^{3} }[/tex]
   r = 4 cm

8. V = [tex]r^{3}[/tex]
   V = [tex]15^{3}[/tex]
   V = 3.375 [tex]cm^{3}[/tex]  
   Lp = 6 × [tex]r^{2}[/tex]
   Lp = 6 × [tex](15 cm)^{2}[/tex]
   Lp = 1.350 [tex]cm^{2}[/tex]

9. V = La × t
   V = ( 10 cm × 3 cm ) × 15 cm
   V = 450 [tex]cm^{3}[/tex]

10. a. limas segi lima = 6 sisi
    b. limas segi enam = 7 sisi

11. V = La × t
   V = ( 1/2 × 3 cm × 4 cm ) × 15 cm
    V = 90 [tex]cm^{3}[/tex]
