Question

Write the equation for a circle with a center at (5,-2) and a radius of 4.

Answer 1

Answer:

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

Step-by-step explanation:

The equation of a circle is: $( x - h )^2 + ( y - k )^2 = r^2$ where ( h, k ) is the center and r is the radius. Therefore, the equation in this instance is $(x-5)^2+(y+2)^2=4^2$.
