Question

Given that circle P has a radius of 7 and a center of (3, -2), which point lies on the perimeter of circle P?

A. (3, -9)
B. (4, 2)
C. (3, -2)
D. (4, -5)

Answer 1

Answer: (3, -9)

Explanation:

The equation of P is
`(x-3)^2 +(y+2)^2 =49`

Substituting the coordinates of each of the points into the equation, we see that only (3, -9) satisfies the equation.
