Answer:
Step-by-step explanation:
<u>1) Find the radius</u>
We can do this by using the distance equation with the centre (7,1) and the given point (-1,-5):
where the two points are
and
Plug in the points (7,1) and (-1,-5)
Therefore, the radius of the circle is 10 units.
<u>2) Plug the data into the equation of a circle</u>
Equation of a circle (when not centred at the origin):
where the centre is
and r is the radius
Plug in the centre (7,1) as (h,k)
Plug in the radius 10
