Difficulty: Easy
Correct Answer: 25 π
Explanation:
Introduction / Context:
The question combines distance formula in the coordinate plane with the area formula for a circle. First compute the segment length PQ; that length becomes the radius r. Then evaluate area = π * r^2.
Given Data / Assumptions:
Concept / Approach:
Use r = sqrt[(x2 − x1)^2 + (y2 − y1)^2]. Then square r to compute area. This avoids working with square roots at the end since r^2 is needed directly in the area formula.
