K = π × d
K = 22/7 × 14 + 14
K = 44 : 4 + 14
K = 25 cm

Jawab:
≈ 25 cm
Penjelasan dengan langkah-langkah:
Dik: jari-jari (r) = 7 cm
π ≈ 22/7
Dit: keliling
Keliling =
dua jari-jari + seperempat lingkaran
2r + (2πr/4) =
2r(1 + π/4) ≈
(2×7)×(1 + (22/7)/4) ≈
14 × (1 + 22/28) ≈
14 × (28/28 + 22/28) ≈
14 × 50/28 ≈
50/2 ≈
25 cm
