Penjelasan dengan langkah-langkah:
rumus mencari keliling lingkaran = 2πr / π × d
Keliling lingkaran = 2 × 22/7 × 7
[tex]2 \times \frac{22}{7} \times 7 \\ = 2 \times 22\\ \\ = 44 \times \frac{1}{4} \\ = 11 \: cm[/tex]
= 2 × 44
= 44 × ¼
= 11 cm
Cara 2
= ¼ × 2 × 22/7 × 7
= 11/7 × 7
Kesimpulan Jadi keliling lingkaran = 11 cm

[Keliling Lingkaran]
Penjelasan dengan langkah-langkah:
Pendahuluan :
rumus mencari keliling lingkaran = 2πr / π × d
Penyelesaian :
Cara 1
Keliling lingkaran = 2 × 22/7 × 7
[tex]2 \times \frac{22}{7} \times 7 \\ = 2 \times 22\\ \\ = 44 \times \frac{1}{4} \\ = 11 \: cm[/tex]
= 2 × 44
= 44 × ¼
= 11 cm
Cara 2
= ¼ × 2 × 22/7 × 7
= 11/7 × 7
= 11 cm
Kesimpulan Jadi keliling lingkaran = 11 cm
