Diketahui
Lingkaran Rasel. r = 14 cm
Lingkaran Nisa r = 2 x 14 cm = 28 cm
Ditanya selisih keliling lingkaran tersebut?
Jawab
Lingkaran Rasel
Kll = 2 x π x r
Kll = 2 x 22/7 x 14
Kll = 2 x 22 x 2
Kll = 88 cm
Lingkaran Nisa
Kll = 2 x 22/7 x 28
Kll = 2 x 22 x 4
Kll = 176 cm
Jadi selisih lingkaran mereka adalah 176 - 88 = 88 cm
