Free SAT Circles Practice Questions
Circle questions on the SAT split into two kinds: equations of circles in the coordinate plane, usually requiring you to complete the square, and arc, sector and central-angle relationships as fractions of the whole circle.

Preparing the question set…
Try three questions before signing in. Your first miss opens a hint; the full solution stays sealed until you solve or reveal it.
How the SAT tests circles
You convert between general and standard circle equations, identify center and radius, and compute arc length and sector area from a central angle.
Where the points go
Reading the radius directly off the equation when the constant is r squared, and using diameter where the formula wants radius.
Every question you miss here is added to your mistake log with the specific error identified, and brought back after three days and again after fourteen — no screenshots, no error journal to keep.
