Question

A square is inscribed inside a circle as shown. If graphed on the coordinate plane, the coordinates of the endpoints of the diameter would be (2, 1) and (5,5). Find the area of the circle.
A)
5π


B)
6.25π


C)
8π


D)
10π

Answer 1

Answer:

B

Step-by-step explanation:

Diameter:

sqrt[(5-2)² + (5-1)²]

sqrt(9+16)

sqrt(25) = 5

Radius = 5/2 = 2.5

Area = π × 2.5² = 6.25π
