Question

Ariel bought a new bike. The wheels have a diameter of 20 inches. How far will the bike travel if the wheel rotates one time around?

Answer 1

Answer:

$distance\ travel\ by\ bike = 62.8\ inches$

Step-by-step explanation:

Let x be the distance travel by bike to rotate wheel once.

Given:

Diameter of the wheel = 20 inches

The distance travel by bike to rotate wheel one time = circumference of the wheel

$x= circumference\ of\ a\ wheel$

Circumference of the wheel = $\pi \times d$

where d is the diameter of the wheel.

Circumference of the wheel = $\pi \times 20$

Used $\pi =3.14$

Circumference of the wheel = $3.14 \times 20$

Circumference of the wheel = $62.8\ inches$

$x=62.18\ inches$

Therefore, the distance travelled by bike to rotate wheel once is 62.8 inches.
