Answer:

Step-by-step explanation:
We have been given that a circle has its center at (−2, 5) and a radius of 4 units. We are asked to write the equation of the circle.
We know that standard equation of circle is in form
, where, (h,k) represents vertex of circle and r represents radius of circle.
Upon substituting coordinates of vertex
and
in above equation, we will get:


Therefore, the equation of our given circle would be
.
