Panjang diameter (D) = K / π

Panjang jari-jari (r) = K / (2π)

1. K = 110 cm

D = K / (22/7) = 110 cm / (22/7) = 35 cm

r = D / 2 = 35 cm / 2 = 17.5 cm

2. K = 157 cm

D = K / 3.14 = 157 cm / 3.14 = 50 cm

r = D / 2 = 50 cm / 2 = 25 cm

3. K = 264 cm

D = K / (22/7) = 264 cm / (22/7) = 84 cm

r = D / 2 = 84 cm / 2 = 42 cm

4. K = 235.5 cm

D = K / 3.14 = 235.5 cm / 3.14 = 75 cm

r = D / 2 = 75 cm / 2 = 37.5 cm

5. K = 308 cm

D = K / (22/7) = 308 cm / (22/7) = 98 cm

r = D / 2 = 98 cm / 2 = 49 cm
