In this worksheet, students will practice circles in a fun Sudoku puzzle. They will practice finding the center and the radius of circles when in center-radius form and in general form. When in general form, students will need to "complete the square" to convert to center-radius form.
The student directions on the puzzle state: Solve each problem and place the remainder in the indicated column and row of the puzzle. (You may need a scrap sheet of paper for your work.) When finished, solve the remaining Sudoku puzzle. Remember, each row, each column, and each 3x3 square should have the numbers 1 – 9, with no repetition. Hint: Answers should be positive integers.
An answer key is included for easing grading!
