Question

Tire has diameter of 5cm. How far does it travel after 1 rotations

Answer 1

15.7cm

Explanation:

Diameter of the tire = 5cm

Radius of the tire = 5/2 cm

Since a tire travels it's own circumference in each rotation,

Distance traveled in one rotation = 2 × pi × r

=2 × 22/7 × 5/2

=3.14 × 5

= 15.7cm

Answer 2

`\[ \text{Circumference} \approx 3.14 * 5 \, \text{cm} \]`

`\[ \text{Circumference} \approx 15.7 \, \text{cm} \]`

So, the tire travels approximately 15.7 cm after one rotation.
