Question 1 · 1 mark · Difficulty 1/3

What does the equation x² + y² = 25 represent?

  1. A circle, centre origin, radius 5
  2. A circle, centre origin, radius 25
  3. A parabola
  4. A straight line
Show answer & explanation
✓ Answer: AA circle, centre origin, radius 5
x² + y² = r² is a circle centred at the origin with radius r. Here r² = 25, so r = 5.
Question 2 · 1 mark · Difficulty 1/3

The equation of a circle centred at the origin with radius 10 is:

  1. x² + y² = 100
  2. x² + y² = 10
  3. x² + y² = 20
  4. x + y = 10
Show answer & explanation
✓ Answer: Ax² + y² = 100
r² = 10² = 100, so x² + y² = 100.

AQA GCSE Mathematics: Graphs of circles and other implicit curves FAQ

How many AQA GCSE Mathematics questions on Graphs of circles and other implicit curves are there on Kramizo?
Kramizo currently has 20 exam-board-aligned practice questions on Graphs of circles and other implicit curves for AQA GCSE Mathematics, with new questions added every week. Each question gives you instant feedback and a full examiner-style mark scheme that tells you exactly what would earn marks on a real AQA paper. The questions span the full difficulty range — from straightforward recall (level 1) right up to multi-step reasoning and evaluation (level 3) — so the bank works for first-pass revision and final exam-week stress testing alike.
Is Kramizo free for AQA GCSE students preparing for Mathematics?
Yes — completely free. Every student gets 45 questions a day on the free plan, with no card required and no trial countdown. That free quota works across every subject and every topic in our bank, so you can mix Graphs of circles and other implicit curves practice with other Mathematics topics or even switch to a totally different AQA subject without paying anything. Kramizo's optional Pro plan removes the daily cap and adds detailed progress analytics, but the free tier is the real product — used by thousands of GCSE, IGCSE and CSEC students.
Are the Graphs of circles and other implicit curves questions aligned to the official AQA GCSE Mathematics syllabus?
Every question is written against the published AQA GCSE Mathematics specification, including the exact command words (state, describe, explain, calculate, evaluate, etc.), mark allocations, and difficulty tier you'd see on a real AQA paper. Explanations are written in the style of official examiner mark schemes — they tell you what is being awarded marks and why distractors are wrong, not just whether you got it right. The bank is continually refined to match the latest syllabus updates from AQA.
How is Graphs of circles and other implicit curves typically tested on AQA GCSE Mathematics papers?
Graphs of circles and other implicit curves appears across multiple question types on real AQA GCSE Mathematics papers — most commonly as multiple-choice questions in the objective section, structured short-answer questions in the main paper, and occasionally as part of an extended response. Kramizo's practice bank reflects that mix: 4-option MCQs, true/false statements, fill-in-the-blank key terms, multi-select questions, and ordering questions. Working through the bank gives you exposure to every question style examiners actually use.
