So in this problem, we're looking at a car's wheel, which is just a circle.
00:06
We know the diameter of that wheel will be 28 inches.
00:12
In this case, we want to know how far you will travel if the wheel goes around 10 ,000 times.
00:23
Well, if i know the distance around the circle once, that would give me the distance that you would travel after one revolution.
00:33
So the circumference will be the distance traveled after one rotation.
00:49
Well, i know that the circumference of a circle is pi times the diameter, which in this case is 28 pi inches.
00:59
So one revolution will be 28 pi inches.
01:05
But we want to rotate around 10 ,000 times.
01:10
So i'm going to take 28 pi and multiply by 10 ,000, which will give me 280 ,000 inches.
01:31
So we need to convert this to miles...
