Question 176191
So what you are being told in the problem is that the circumference of the table is 50*pi.  Remember that the formula for the circumference of a circle is 2*pi*r, or pi*d (diameter).  Since we are wanting to solve for the radius, let's just use the first formula.  So we have
{{{2*pi*r=50*pi}}}
We are solving for r, so divide both sides by 2*pi:
{{{r=(50*pi)/(2*pi)=25}}}
So the radius is 25 inches.
