Jika kelilingnya 56 maka diameter dan jari jarinya? Pakai cara 22/7
![]()
Penjelasan dengan langkah-langkah:
keliling lingkaran = 2 π r
Keliling Lingkaran = 56
[tex]2 \times \pi \times r = 56 \\ 2 \times \frac{22}{7} \times r = 56 \\ \frac{44}{7} \times r = 56 \\ r = \frac{56 \times 7}{44} = \frac{392}{44} = \frac{98}{11} \\ maka \: diameter \: = 2 \times r \\ diameter \: = 2 \times \frac{98}{11} = \frac{196}{11} [/tex]
