Answer:

The circumference of Bob's new wheel is 81.7 inches

Step-by-step explanation:

Circumference of a circle

The circumference of a circle of radius r is given by:

[tex]C=2\pi r[/tex]

The radius is half the diameter:

r = d / 2 = 26 / 2 = 13

r = 13 inch

Now calculate the circumference:

[tex]C=2\cdot\pi\cdot 13[/tex]

Calculating:

[tex]C=81.7\ inch[/tex]

The circumference of Bob's new wheel is 81.7 inches
