1. The problem statement, all variables and given/known data Find the radius of a circle inscribed in a quadrant of a circle with radius 5 2. Relevant equations 3. The attempt at a solution I worked this but I'm not sure if its correct. I looked at the first quadrant so a quarter of a circle with radius 5. I drew the radius that would bisect the angle at the origin into 45° angles. I found the midpoint of the radius and dropped a line to the x-axis from that midpoint. This forms a 45-45-90 triangle which would make the radius of the inscribed circle 2.5/√2. Is this correct??
