Question 1 of 50
1. Question
Topic: Area of a Circle
-
Area = mm²
⌨️ Enter your answer in the field provided.
CorrectIncorrectHint
💡➡️ For area of a circle questions, first check whether the given length is the radius or the diameter.
⭕ The radius is the distance from the centre of the circle to the edge.
↔️ The diameter is the full distance across the circle through the centre.
✂️ If you are given the diameter, divide it by 2 to find the radius.
🧠 Use the formula area = π × radius².
🔢 Square the radius first, then multiply by π.
🧮 Use the π button on your calculator if the question allows a calculator.
✅ Finish with square units, such as cm², because area measures the space inside the circle.

💡➡️ For area of a circle questions, first check whether the given length is the radius or the diameter.
⭕ The radius is the distance from the centre of the circle to the edge.
↔️ The diameter is the full distance across the circle through the centre.
✂️ If you are given the diameter, divide it by 2 to find the radius.
🧠 Use the formula area = π × radius².
🔢 Square the radius first, then multiply by π.
🧮 Use the π button on your calculator if the question allows a calculator.
✅ Finish with square units, such as cm², because area measures the space inside the circle.
