d. a. b. e. c. f. What is the center and radius of the circle described below? Radius should be written in simplest radical form. ( example: 3root2 ) Center: ( , ) Radius: How long is the radius of this circle? What is the perimeter of the quadrilateral? perimeter= x= How long is the radius of this circle? hint: leave x as a fraction to compute the length of KN. What is the value of x (that makes sense) ? x= |
