Question

A circle is represented by the equation shown below.

Answer 1

Answer:

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
