Answer:
B.
R (2,4)
soln
center(h,k)=(6,1)
radius (r)=5units
so
eqn of circle is (x-6)^2+(y-1)^2=5^2
2 2
or, 25=x +y -12x-2y+36+1 now , only the given point (6,1)satisfies the eqn so this point lies on circle
D. X=18
Exp:
16-X=-2
-16 -16
-X=-18
X=18
Answer:
; k=25
Step-by-step explanation:

7 less than 25 (or K) is 18.
Plane it has to with in 5
