semoga bermanfaat
Sudut pusat dihadapan sudut 60
= 1/2(360 -60)
= 1/2(300)
= 150 derajat
r = 14 cm
Dijawab :
Panjang busur = keliling lingkaran x 60/360
= 2πr x 1/6
= 2 . 22/7 . 14 . 1/6
= 88/6
= 14,6 cm
B. Dik : r = 14 sudut = 60
Dit : Luas juring
Jwb : LO = 22/7 x 14 x 14 = 616 cm2
60/360 x 616 = 616/6 = 102,6 cm2.
Kalo salah maaf :)
