Keliling roda = phi x D = 22/7 x 70 = 220
berputar 200 kali maka 220 x 200 = 44000 cm = 440 meter

Diameter = 70cm jari jari = 70:2 = 35cm keliling= 22/7 x 35cm = 110cm 200x110cm = 22.000cm = 22m

jawaban ane salah 22/7 x 70 = 220 × 200 = 44.000cm=440m
= phi x D
= 22/7 x 70
= 220
berputar 200 kali maka
220 x 200 = 44000 cm = 440 meter
jari jari = 70:2 = 35cm
keliling= 22/7 x 35cm = 110cm
200x110cm = 22.000cm = 22m
