Two circles are concentric if they have the same center.

Which equation represents a circle that is concentric with

the circle shown but has a radius that is twice as large?

(x – 4)2 + (y - 6)2 = 4

(x – 4)2 + (y - 6)2 = 16

(x - 6)2 + (y – 4)2 = 16

O (X - 6)2 + (y - 4)2 = 4

range is infinite on both x and y axis positive and negative

step-by-step explanation:

place r′ so that qr′ is parallel to the tangent.

now we get that ∠r′py=∠pr′q, where y is on the tangent, on the opposite side of p from x.

also, because of the symmetry, ∠r′py=∠qpx.

finally, note that no matter where we place r, as long as it's on the correct arc, we have ∠prq=∠pr′q.

stringing all these equalities together, we end up with ∠prq=∠qpx.

this picture will show how its going to look like.
