Question

The equation of a circle is (x+10)^2+(y-4)^2=100

Answer 1

Answer:

Correct option is:

1.) Center: (-10,4); Radius: 10

Step-by-step explanation:

The equation of the circle centered at (a,b) and radius r is:

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

Here, we are given a equation:

$(x+10)^2+(y-4)^2=100$

On comparing this equation with the above equation, we get

a= -10

b=4

and r=10

Hence, Center of circle= (-10,4)

and Radius=10

Hence, Correct option is:

1.) Center: (-10,4); Radius: 10
