Question

This circle is centered at the point (4, 5), and the length of its radius is 3. What is the equation of the circle

Answer 1

( x - 4 )^2 + ( y - 5 )^2 = 9

i am a mathematics teacher. if anything to ask please pm me

Answer 2

Using the equation:
(x−h)^2+(y−k)^2=r^3

r is the radius and (h,k) is the vertex.
Substituting the values:
We get;
(x−4)+(y−5)=9
