Question

Diameter GH with has endpoints G (-5,-7) and H (11,5). The radius of the circle is 10 units in length, with a center of (3,-1). Which of the following is the equation of the circle?

Answer 1

Given

radius of the circle is 10 units.

Center(3,-1)

Find

equation of the circle.

Explanation

As we know that the equation of the circle is given by

$(x-h)^2+(y-k)^2=r^2$

where (h , k) is the center and r is a radius.

so , equation of the circle =

$(x-3)^2_+(y+1)^2=10^2$

Final Answer

The equation of the circle =

$(x-3)^2_+(y+1)^2=10^2$

so , the correct option is 4.
