A bicycle tire rim has a diameter of 24.5 inches, and the tire is 2.25 inches thick. Find the circumference of the outside of the tire.

To find the circumference of the outside of the tire, we need to add the diameter of the rim to the thickness of the tire.

The diameter of the rim is given as 24.5 inches, so the radius of the rim is half of this value, which is 24.5 / 2 = 12.25 inches.

The thickness of the tire is given as 2.25 inches.

To find the circumference, we can use the formula:
Circumference = 2 * pi * radius.

Substituting in the values we have:
Circumference = 2 * 3.14159 * 12.25 + 2.25 = 2 * 3.14159 * 12.25 + 2.25

Therefore, the circumference of the outside of the tire is approximately 77.154 inches.

To find the circumference of the outside of the tire, you need to add the circumference of the rim to the circumference of the tire.

First, let's find the circumference of the rim. The formula for the circumference of a circle is C = πd, where C is the circumference and d is the diameter.

Given that the diameter of the rim is 24.5 inches, we can calculate the circumference of the rim using the formula:

C_rim = π * d_rim
= π * 24.5 inches

Now, let's find the circumference of the tire. The thickness of the tire does not affect the circumference of the outer edge. So, we can use the same formula:

C_tire = π * d_rim
= π * 24.5 inches

Finally, to find the total circumference of the outside of the tire, we add the circumference of the rim and the circumference of the tire:

C_total = C_rim + C_tire
= (π * 24.5 inches) + (π * 24.5 inches)
= 2 * (π * 24.5 inches)
= 49π inches

Therefore, the circumference of the outside of the tire is 49π inches.

well, the diameter of the outside is d = 24.5 + 2*2.25

since there is tire all the way around.
Now you can get the circumference: pi * d

D = 29

C = pi * 29
C = 91.06 inches
