kak ini gimana ya rumusnya............................................
Note!!
- r = jari-jari = 7 cm
Luas Lingkaran :
[tex] = \pi {r}^{2} \\ = \frac{22}{7} \times 7 \times 7 \\ = 154 \: {cm}^{2} [/tex]
Keliling Lingkaran :
[tex] = 2\pi {r}^{2} \\ = 2 \times \frac{22}{7} \times 7 \\ = 2 \times 22 \\ = 44 \: cm[/tex]
Jawaban:
[tex]2 \times \pi \times r \: = k \\ \pi \times {r}^{2} = l[/tex]
