Tolong jawab . Pakai cara .

r
35cm : luas : keliling : cara
40cm : luas : keliling : cara
56cm : luas : keliling : cara​

Jawaban:

[tex]k = 2\pi \: r \\ k = 2 \times \frac{22}{7} \times 35 = 220cm[/tex]

[tex]l = \pi {r}^{2} \\ l = \frac{22}{7} \times 35 \times 35 = 3.850[/tex]

[tex]k = 2\pi \: r \\ k = 2 \times 3.14 \times 40 = 251,2[/tex]

[tex]l = \pi {r}^{2} \\ l = 3.14 \times 40 \times 40 = 5.024[/tex]

[tex]k = 2\pi \: r \\ k = 2 \times \frac{22}{7} \times 56 = 352[/tex]

[tex]l = \pi {r}^{2} \\ l = \frac{22}{7} \times 56 \times 56 = 9.856[/tex]

semoga membantu
