Select the correct answer. Which point lies on a circle with a radius of 5 units and center at P(6, 1)? A. Q(1, 11) B. R(2, 4) C

jasenka [17]

Answer:

T(9,-2)

Step-by-step explanation:

The circle has radius 5 units and center P(6,1).

The equation of this circle is

$(x-6)^2+(y-1)^2=5^2$

$(x-6)^2+(y-1)^2=25$

If Q(1,11) lies on this circle, then it must satisfy its equation.

$(1-6)^2+(11-1)^2=25$

$(-5)^2+(10)^2=25$

$25+100=25$ , this statement is false.

If R(2,4) lies on this circle, then it must satisfy its equation.

$(2-6)^2+(4-1)^2=25$

$(-4)^2+(3)^2=25$

$16+9=25$ , this statement is false.

If S(4,-4) lies on this circle, then it must satisfy its equation.

$(4-6)^2+(-4-1)^2=25$

$(-2)^2+(-5)^2=25$

$4+25=25$ , this statement is false.

If T(9,-2) lies on this circle, then it must satisfy its equation.

$(9-6)^2+(-2-1)^2=25$

$(4)^2+(-3)^2=25$

$16+9=25$ , this statement is TRUE.

The correct answer is D
