Penjelasan dengan langkah-langkah:
Luas juring = (sudut pusat / 360°) x Luas lingkaran
301.44 = (60/360) x Luas lingkaran
301.44 = (1/6) x Luas lingkaran
Luas lingkaran = 301.44 ÷ (1/6)
Luas lingkaran = 301.44 x 6
Luas lingkaran = 1808.64
3.14 x r² = 1808.64
r² = 1808.64/3.14
r² = 576
r = V576 = 24
Keliling = 2 x 3.14 x 24
Keliling = 150.72
Panjang busur = (60/360) x 150.72
Panjang busur = (1/6) x 150.72
Panjang busur = 25.12 cm
