Question

the diameter of a circle is 16, and its center is located at (-2,-6) what is the equation of the circle?​

Answer 1

(x+2)² + (y+6)² = 64

Given:

• centre : (-2,-6)

• diameter : 16

• radius : 8

=============

Formula's:

• (x-h)² + (y-k)² = r²

• centre : (h, k)

• radius : r

===========

equation:

• ( x - (-2))² + (y-(-6))² = 8²

• (x+2)² + (y+6)² = 64
