The diameter of a circle has endpoints whose coordinates are r(-2, 2) and s(4, 2). the radius of the circle has length a.  3 b.6c.9.

A.3

Step-by-step explanation:

Hello

I think i can help you with this

step 1

to find the diameter  use the distance between two points formula

let

the distance between P1 and P2 is

Now,replacing

P1(-2,2)  P2(4,2)

step 2

with the diameter we can find the radius

isolating r

and replacing

the radius of the circle is 3

A.3

dunno

it's both, now can you answer my most recent question?
