Hello students, here we have a tyre that has a diameter t equal to 2 feet and the warranty period of the tyre is 60 ,000 miles.
00:16
So, from this we can first determine the angle through which one of the tyre will rotate during the warranty period.
00:26
So, we have to determine the angle in radians.
00:35
So, we can write first we have to calculate the circumference of the tyre.
00:43
So, c equal to 2 pi r.
00:49
So, we can write 2 pi into 1 feet that is equal to 2 pi feet.
01:01
So, from this we can get the angle in radians.
01:05
So, we can write angle equal to arc length divided by radius r.
01:17
So, from this we can during the warranty period we know that the length is 60 ,000 miles.
01:34
So, to convert this distance to feet first we have to multiply it by 5280...
