Jawaban:
d. 135°
Penjelasan dengan langkah-langkah:
Dik: Busur AB = 16.5 cm, r = 7 cm
Dit: x = ?
Jawab:
Perbandingan panjang busur AB dan keliling lingkaran sama dengan perbandingan sudut busur dan 360°.
[tex] \frac{\text{busur} \: AB}{2\pi.r} = \frac{x}{ {360}^{ \circ} } \\ \frac{16.5}{2 \times 3.14 \times 7} = \frac{x}{{360}^{ \circ} } \\ \frac{6.5}{43.96} = \frac{x}{ {360}^{ \circ} } \\ \frac{16.5 \times {360}^{ \circ} }{43.96} = x \\ {135.1}^{ \circ} = x\\ x = {135.1}^{ \circ} [/tex]
Semoga bermanfaat.
