Bab Bangun DatarMatematika SD Kelas VI
pada lingkaran
keliling = π x d = 22
22/7 x d = 22
d = 22 x 7/22
d = 7 cm
d = s = 7 cm
pada persegi
k = 4 x s
k = 4 x 7
k = 28 cm
jawabannya B
Verified answer
Keliling lingkaran = 2 phi r22 = 2 * 22/7 * r
154 = 44r
r = 3,5 cm
d = 2r = 7 cm = panjang sisi persegi
Maka,
Keliling persegi = 4s
= 4(7)
= 28 cm
