Find the distance between (3,2) and (10,2) using the distance formula (http://www.mathwarehouse.com/calculators/distance-formula-calculator.php) . Using the formula you find the distance of those two points is 7. And the radius can not be seven since 10,2 is out of the circle. You can eliminate E. Then, find the distance between (3,2) and (3,8). The distance is 6. So the radius has to be 6 because (3,8 ) is in the circle [C]
