in form (x-h)²+(y-k)²=r² center is (h,k) and radius is r so center at (0,0) radius 10 is (x-0)²+(y-0)²=10² x²+y²=100 (x+2)²+(y-1)²=4 (x-(-2))²+(y-1)²=2² center is (-2,1) and radius is 2

Circle X centered at the 0,0 with radius 10 all circles centered at (0,0) with radius r has an eqn of x^2 + y^2 = r^2 so in this case, it is x^2 + y^2 = 10^2 = 100 assuming the + is a typo of = (x+2)^2+(y-1)^2 = 4 means (x -(-2))^2 + (y-1)^2 = 2^2 the radius is 2 for circle with center at (h,k), its eqn is (x-h)^2 + (y-k)^2 = r^2 so the center in this case is (-2,1)
