The distance that the train travels is 18.84 feet
Solution:
Given that,
A play train travels around a Christmas tree in a circle
The train track measures 6 feet in diameter
To find: distance that the train travels
The distance the train travels is equal to the circumference of circle
The circumference of circle is given as:
[tex]C = \pi d[/tex]
Where, "d" is the diameter of circle
From given,
d = 6 feet
[tex]C = 3.14 \times 6\\\\C = 18.84[/tex]
Thus the train travels 18.84 feet
