Tolong jawab ya kakak’ pliss besok pagi di kumpulkan
Jawaban:
22. D) layang-layang.
23. K= a+b+c+d
= 32+10+16+10
= 68 cm (B)
24. L= a+b/2 × t
= 59+59/2 × 27
= 1593 cm2 (B)
25. L= 2/6 × pi × r×r
= 2/8× 22/7× 14× 14
= 154 cm2 (D)
26. K= (3/4 × pi × d) + r + r
= (3/4×22/7×200) +100+100
= 3300 + 200
= 3500 (?)
27. K= 2× (p+l)
= 2 ×(23+15)
= 2× 38
= 76 ÷ 4
= 19 buah (A)
28. Lp= 2 × {(p×l)+(p×t)+(l×t)}
= 2 × {(21×17)+(21×14)+(17×14)}
= 2 × (357+294+238)
= 2 × 889
= 1778 cm2
