    Question Finding a circles radius,diameter,... .:Resolved:.

    Hello everyone, I havn't had algebra 2 in awhile and I forgot how to use the distance formula which is: sqrt((x2-x1)^2+(y2-y1)^2));
    (x1,y1) and (x2,y2) are points. Given the center and a point on the circle how can i find the distance, radius, circumference, and area? Can someone give me an example of using this formula? Then i'll remeber! Thanks!
