Answer:

= 2449.2 inches

Explanation:

1 revolution is equivalent to the circumference of the wheel

Circumference = 2πr

Radius = 13 inches

1 revolution = 2 × 3.14 × 13 inches

= 81.64 inches

30 revolutions = 81.64 inches × 30

= 2449.2 inches

Answer:

2449.2 inches

Explanation:

The distance the bicycle wheel covers in one revolution is equal the the circumference of the bicycle wheel which is given by;

$C=2\pi r$

We substitute r=13 inches, which is the radius of the wheel
$\pi=3.14$ into the formula to get;

C=2(3.14)(13)

$\Rightarrow C=81.64$

After 30 revolutions, the bicycle will cover;

81.64* 30=2449.2in
