This circles review worksheet is pretty fantastic because of the variety of question types and the broad spectrum of material it covers.
It is a word document so if there are concepts that don't fit into your states core specifically you can edit the document.
It starts with a matching section reviewing the equation of a circle when given a variety of information such as:
_________ Find the equation of a circle whose center is at (5,-1) and radius 3.
_________ Find the equation of a circle that has a diameter with endpoints (-4,-2)and (4,2).
Next students are asked to complete the square to write the equation of a circle in standard form such as this:
Write the equation x^2+y^2-6x-4y-12=0 in the standard form of (x-h)^2+(y-k)^2=r^2.
Next there is some questions about identifying vocabulary on the parts of the circle.
Next students will solve a system of equations with a line and a circle as the equations.
Next students are asked to identify volume formulas.
And finally there is arc length and sector area questions.
