Best answer

Radius of the wheel = 20 cm

When the wheel rotates once it will travel the distance same as its area

Perimeter of the wheel = 2 × π × radius = 2 × 3.14 × 20 = 125.64 cm

The distance travelled forward when the wheel rotates once = 125.64 cm

The distance travelled forward when the wheel rotates 10 times

= 125.64 × 10 = 1256.4 cm
