Jawab:
B. 6 cm
Penjelasan dengan langkah-langkah:
Diketahui
Kll = 18,84 cm
Ditanya d = ?
Jawab
Cara 1
Kll = π x d
18,84 = 22/7 x d
1884/100 = 22/7 x d
d = 1884/100 : 22/7
d = 1884 /100 x 7/22
d = 13.188/2200
d = 5,99 = 6 cm
Cara 2
Kll = π x d
18,84 = 3,14 x d
d = 18,84 : 3,14
d = 6 cm
B. 6 cm
____________________________
Keliling = π × d
18,84 = 3,14 × d
d = 18,84 : 3,14
d = 6 cm
