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:

Where, "d" is the diameter of circle

From given,

d = 6 feet

Thus the train travels 18.84 feet

168

step-by-step explanation:

first off, we know that he drove 3.5 hours at a rate of 48 mph.

knowing that, we want to see how many miles he drove all-together.

in this case, we can just multiply 48 by 3.5.

48 * 3.5 = 168
