Step-by-step explanation:

Answer: 530.7 sq.units.

Step-by-step explanation: Let O(5, -3) be the centre of the given circle, and A(-7, 2) be a point on the circumference of the circle. ...

Using distance formula,

OA = √(5+7)²+(-3-2)² = √144+25 = √169 = 13 units.

∴, area of the circle is A = π(OA)² = 3.14 × 169 = 530.7 sq.units.
