Question 82576
First, find how many inches around (circumference) is the
entire circle. Use formula {{{C = 2*pi*r}}}
{{{C = 2*3.141*45}}}
{{{C = 282.7}}} in
How long is the arc in inches?
{{{1.667*12 = 20}}} in
Find ratio of arc to circumference
{{{20 / 282.7 = .0708}}}
There are 360 degrees in a circle
arc in degrees / 360 = .0708
arc in degrees = .0708 * 360
{{{.0708*360 = 25.47}}}degees answer
