Question

circle question, picture drawn below

Answer 1

make clear ur question plz

Answer 2

i need to figure out the centre of the secon circle, i have the centre of the first one and its radius, also the circles are congruent so i think thet have the same radiuses

Answer 3

wts the value of ur 2 different circle

Answer 4

circle 1 has a radius of \[2\sqrt{10}\]as does circle 2, circle 1 has a centre point of (3,1)

Answer 5

the equation of circle 1 is x^2 + y^2 -6x - 2y- 30=0

Answer 6

the two triangles are congruent.
Use distance formula twice to solve for (x,y)

Answer 7

or method 2:
\[(x-h)^2+(y-k)^2=(2\sqrt{10})^2\]
this circle passes through two points....
so, get two equations and sole for (h,k)

Answer 8

Method 2:\[
(-3-h)^2+(-1-k)^2=40\\
(3+h)^2+(1+k)^2=40\qquad\text{simplify}\\
(1-h)^2+(7-h)^2=40\qquad\text{simplify}
\]
solve the two equations

Answer 9

method 1 will give you the same equations.
Method 3:
use t-ratios

Answer 10

Method 3 will be more tedious though
