Step-by-step explanation:
We know that the circumference of the circle is 2πr and it is given that r=10
∴C=20π
The circumference of the circle is 20π units
The arc length is between 5 and 6, which is what percent of the circumference that is
20π
5
=0.07957747154594766788444188168626
20π
6
=0.09549296585513720146133025802351
There are 360 degrees in a circle, therefore,
360×.0796=28.656
degrees
360×.0955=34.38 degrees
Hence, any integer in between will work that is:
29,30,31,32,33,34
