3. D = 100cm
L = 314/100 x 10 x 10 = 314

4. D = 225cm
L = 314/100 x 15 x 15 = 706,5

5. D = 144cm
L = 314/100 x 12 x 12 = 452,16

6. jari jari = 17,5cm
L = 22/7 x 17,5 x 17,5 = 962,5

7. jari jari = 14cm
L = 22/7 x 14 x 14 = 616

8. jari jari = 15cm
L = 314/100 x 15 x 15 = 706,5

9. jari jari = 17cm
L = 314/100 x 17 x 17 = 907.46

10. jari jari = 20cm
L = 314/100 x 20 x 20 = 1256

ps = setiap jawaban dari luas diberi 'cm (kuadrat)'
