bagi yang pandai matematika
makasih ☺​

6. \frac{12}{180}  =  \frac{3}{x}

180 x 3= 12 x X

X = \frac{540}{12}

3 kg mangga = 45.000

Maka = 50.000-45.000

=Rp. 5.000,00 (A)

7. jp ÷ s

js = 14 ÷  \frac{1}{500}

js = 14 ×  \frac{500}{1}

js = 7.000 cm

js = 70m (diamater)

js = 35m (jari jari)

luas sebenarnya

= πr²

=  \frac{22}{7} ×35×35

= 3.850 m² (C)

8.

 \frac{20}{25} =  \frac{x}{15}

20 x 15= 25 x X

=300 : 25

=12 (A)

9. C= \frac{5}{4}  \times r

 \frac{5}{4}  \times 64

=  \frac{320}{4}

=80 (D)
