Question

The circle below is centered at (3, 1) and has a radius of 2. What is its
equation?

Answer 1

( x-3) ^2 + ( y-1) ^2 = 4

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-3) ^2 + ( y-1) ^2 = 2^2

( x-3) ^2 + ( y-1) ^2 = 4
