Answer:radius =10 units
Step-by-step explanation:
Given
Equation of circle is given by
[tex](x-13.4)^2+(y+2.6)^2=100\quad \ldots(i)[/tex]
Now general equation of circle with center [tex](h,k)[/tex] with radius [tex]r[/tex] is given by
[tex](x-h)^2+(y-k)^2=r^2\quad \ldots(ii)[/tex]
Comparing [tex](i)[/tex] and [tex](ii)[/tex] we get
[tex]h=13.4[/tex]
[tex]k=-2.6[/tex]
[tex]r=10[/tex]
Thus center is [tex](13.4,-2.6)[/tex]
and radius [tex]r =10\ units[/tex]
