Bangun Datar

[Lingkaran dan Trapesium]

..

[tex]Luas = set.lingkaran + trapesium[/tex]

[tex]Luas = ( \frac{1}{2} \times \pi \times r {}^{2} ) + ( \frac{a + b}{2} \times t)[/tex]

[tex]Luas = ( \frac{1}{2} \times \frac{22}{7} \times 14 {}^{2} ) + ( \frac{36 + 28}{2} \times 6)[/tex]

[tex]Luas = ( \frac{11}{7} \times 196) + ( \frac{64}{2} \times 6)[/tex]

[tex]Luas = 308 + 192[/tex]

[tex]Luas = \boxed{500 \: cm {}^{2} } \: \: \: \: \: opsi \: c[/tex]

Answer 2

Jawaban:

C.

Penjelasan dengan langkah-langkah:

L = ½ x πr² + a+b/2 x t

= ½ x 22/7 x 14² + 36 + 28/2 x 6

= 308 + 192

= 500 cm²
