r = 63 cm
Keliling lingkaran
K = 2 × π × r
K = 2 × 22/7 × 63
K = 2 × 22 × 9
K = 44 × 9
K = 396 cm
Jawaban:
[tex] \sf \: k = 2\pi \: r[/tex]
[tex] \sf \: k \: = 2 \times \frac{22}{7} \times 63[/tex]
[tex] \sf \: k \: = 2 \times \frac{22}{ \cancel7} \times \cancel{63}^{9} [/tex]
[tex] \sf \: k = 2 \times 22 \times 9[/tex]
[tex] \sf \: k \: = 44 \times 9[/tex]
[tex] \sf \red{k = 396 \: cm}[/tex]
