# A circular lock washer whose outside circumference measures 5.48 cm is used is used in an electric box to hold an electrical cable in place. Use your calculator value of π to find the length of the radius of the disk to the nearest tenth of a cm.

To determine

To Find:

The length of the radius of circular washer.

Explanation

Given:

The circumference of the circle is 5.48 cm.

Formula:

The circumference of a circle is C=2Ï€r.

Calculation:

The calculator value of Ï€ is 3.142857.

5.48=2â‹…3.142857â‹…r.

Then the circumference of circle is,
