Perhatikan gambar di samping! jika jari jari lingkarangnya 28cm, tentukan: A. panjang busur AB B. luas daerah arsir ( luas juring AOB ) tolong jawab ya penting

AB = sudut/360.K AB = 120/360.2.phi.r AB = 1/3.2.22/7.28 AB =58,67
Luas = sudut/360.phi.r.r =120/360.22/7.28.28 = 1/3.22.4.28 = 821,33
AB = 120/360.2.phi.r
AB = 1/3.2.22/7.28
AB =58,67
Luas = sudut/360.phi.r.r
=120/360.22/7.28.28
= 1/3.22.4.28
= 821,33
Cek lagi perhitungannya :)
