Question

a circle with center (1,5) passes through the point (10,10). what is the area of the circle rounded to the nearest square unit?

Answer 1

The radius will equal the distance from the center(1,5) to the point on the circle(10,10)

`\sqrt{(10-1)^(2) + (10-5)^(2) }`

`√(81 + 25) = √(106)`
The radius is
`√(106)`
area =
`\pi r^(2)`

`106 \pi`

503 units^2
