Question

A circle with a diameter of 10 has its center in the first quadrant. The lines y = -3 and x = -1 are tangent to the circle. Write an equation of the circle.

Answer 1

34

Explanation:

Answer 2

(h,k)=(-1,-3)

radius =10/2=5 unit

equation of the circle

(x-h)² +(y-k)²=r²

(x+1)²+(y+3)²=25 is a required equation..
