The problem states that a bicycle has tires with a diameter of 26 inches. We need to find the radius and circumference of each tire, rounded to the nearest hundredth.

1. Problem Description

The problem states that a bicycle has tires with a diameter of 26 inches. We need to find the radius and circumference of each tire, rounded to the nearest hundredth.

2. Solution Steps

First, we need to find the radius.

The radius is half of the diameter.

$radius = \frac{diameter}{2}$

$radius = \frac{26}{2} = 13$ inches.

Next, we need to find the circumference.

The formula for the circumference of a circle is:

$circumference = 2 \pi radius$

We already know the radius is 13 inches.

$circumference = 2 \pi (13)$

$circumference = 26 \pi$

Using the value of $\pi \approx 3.14159$, we have:

$circumference \approx 26 \times 3.14159 \approx 81.68134$

Rounding to the nearest hundredth, we get $81.68$ inches.

3. Final Answer

radius: 13.00 in.

circumference: 81.68 in.
