Question

(x-13.4)^2+(y+2.6)^2=100

Answer 1

Answer:radius =10 units

Step-by-step explanation:

Given

Equation of circle is given by

$(x-13.4)^2+(y+2.6)^2=100\quad \ldots(i)$

Now general equation of circle with center $(h,k)$ with radius $r$ is given by

$(x-h)^2+(y-k)^2=r^2\quad \ldots(ii)$

Comparing $(i)$  and  $(ii)$  we get

$h=13.4$

$k=-2.6$

$r=10$

Thus center is $(13.4,-2.6)$

and radius $r =10\ units$
