Find an equation for a circle satisfying the given conditions.
Center (4,5), diameter of length 8.2
Answer by jim_thompson5910(35256) (Show Source): You can put this solution on YOUR website!
If the diameter is 8.2, then the radius is simply half the diameter. So the radius is

Since the center is (4,5), this means that h=4 and k=5. Note: remember, the center of any circle is (h,k)

Start with the general equation of a circle

Plug in , (this is the center) and

Square 4.1 to get 16.81

So the equation of the circle with a center of (4,5) and a diameter of 8.2 units is
