Question

Which is the radius of a circle whose equation is (x-7)^2+(y-10)^2=4

Answer 1

Answer:

2

Step-by-step explanation:

Standard form of a circle   (x-h)^2 + (y-k)^2 = r^2

  this circle is already in this form

     the center will be at   h, k    or   7,10

       the radius^2 = 4     so radius = 2
