# In exercises 34-45, use your calculator value of π unless otherwise stated. Round answers to two decimal places.If two gears, each of radius 4 in are used in a chain drive system with a chain length of 54 in. What is the distance between the centers of the gears.

To determine

To Find:

The distance between the centers of two gears

Explanation

The total chain length is 54 in.

The chain semi circularly covers both the gears.

Therefore, the chain forms a circle over the the gears together.

The radius of the gears is 4 in.

The circumference of the circular chain is C=2Ï€r.

Here, Ï€=3.1416.

Therefore, 2â‹…3.1416â‹…4=25.13
