Question

mencari jari-jari, tapi yg dketahui hnya pnjang busur dan sudut pusat.

pnjang bsur = 10 , sudut pusat = 75

Answer 1

75/360 * π2r = 10
5/24 * π2r = 10
π2r = 24/5 * 10
π2r = 48
2r = 48/π
2r = 132
r = 66 cm

maaf klo jawabannya salah

Answer 2

75/360 * π2r = 10
5/24 * π2r = 10
π2r = 24/5 * 10
π2r = 48
2r = 48/π
2r = 132
r = 66 cm
