option b

Step-by-step explanation:

We have an equation of circle

(x-7)^2+(y-8)^2=121

We have to find the center of given circle and radius

We know that general equation of circle with circle (a,b) and radius r

(x-a)^2+(y-b)^2=r^2

(x-7)^2+(y-8)^2=(11)^2

By comparing given equation with the general equation of circle

We get centre at x=7 and y=8

Radius =11

Hence, the circle is centered at (7,8) and has a radius of 11.

Option b is true
