The radius of a circular car tire is 12.5 in find the circumference. Use 3.14 for n

1 answer

The circumference of a circle is given by the formula C = 2πr, where r is the radius of the circle and π is the mathematical constant pi (approximately 3.14).

Substituting the given values, we get:

C = 2 x 3.14 x 12.5
C = 78.5

Therefore, the circumference of the circular car tire is approximately 78.5 inches.
