Question

What is the equation of a circle with center (2, -5) and
radius 4?

Answer 1

(x-2)^2 +(y+5)^2=4^2

Explanation:

x minus 2 squared + y plus 5 squared = radius squared

Answer 2

(x-2) ^2 + ( y+5)^2 = 16

Explanation:

The equation for a circle is given by

(x-h) ^2 + ( y-k)^2 = r^2 where (h,k) is the center and r is the radius

(x-2) ^2 + ( y- -5)^2 = 4^2

(x-2) ^2 + ( y+5)^2 = 16
