I've been having a hard time with finding the equation from the center and the radius.
I did this one myself using the book to help, but I'm not sure if it's right.
Find the center of the circle whose equation is x2 + y2 – 3x + 8y – 8 = 0 (-3,8)?
These two are similar problems, so I guess I only need help with one.
Write the equation for the circle with the given center and radius.
Center (8, –4), radius 3
Find the equation of a circle centered at (–3, 3) having radius 4.
