Answer:
Circumference = 81.692 inches.
Explanation:
We know that the wheel (tire) of a bicycle is circular in shape.
Hence, the circumference of a circle is its perimeter or ellipse.
Circumference of a circle is given by the formula;
[tex] C = 2\pi r[/tex]
Where, r represents the radius of a circle.
Given the following data;
Diameter = 26 inches
[tex] Radius = \frac {diameter}{2}[/tex]
[tex] Radius = \frac {26}{2}[/tex]
Radius = 13 inches
Substituting into the equation, we have;
[tex] C = 2*3.142 *13[/tex]
Circumference, C = 81. 692 inches.
Method 2
Circumference is given by the formula;
[tex] C = \pi D[/tex]
Where, D represents the diameter of a circle.
Substituting into the equation, we have;
[tex] C = 3.142 *26[/tex]
Circumference, C = 81.692 inches.
