Check the picture below.
recall the diameter is twice as long as the radius, thus d = 2r = 38.42 or rounded up to 38.
<span>in standard form the equation has to be changed from slope-intercept form to standard. bt first you have to find the slope and then change the equation to standard form.
the slope intercet form is y=mx+b using y-k= m(x-h)
and after, change the equation to ax+by+c</span>
