| Topic | Circles |
| Type | Circle equation from centre and radius |
| Difficulty | Easy -1.2 This is a straightforward application of the circle equation formula requiring only calculation of radius using distance formula, then substitution into (x-a)²+(y-b)²=r². It's more routine than average A-level questions since it involves direct formula application with no problem-solving or multi-step reasoning required. |
| Spec | 1.03d Circles: equation (x-a)^2+(y-b)^2=r^2 |
