Keliling lingkaran

r = 14 cm

K = 2 x π x r

K = 2 x 22/7 x 14

K = 2 x 22 x 2

K = 4 x 22

K = 88 cm

r = 10 cm

K = 2 x π x r

K = 2 x 3,14 x 10

K = 6,28 x 10

K = 62,8 cm

d = 49 cm

K = π x d

K = 22/7 x 49

K = 22 x 7

K = 154 cm

d = 25 cm

K = π x d

K = 3,14 x 25

K = 78,5 cm

d = 56 cm

K = π x d

K = 22/7 x 56

K = 22 x 8

K = 176 cm
