X2+y2+4x-24=-1 the equation of a circle in the cycle-plane is the shown above. what is the radius of the circle

For the given equation of circle, radius of circle 3√3 units.

Step-by-step explanation:

Here, the given equation of the circle is

Now, the equation o f circle is given as

Here, (h,k) = Center coordinates

                r = Radius of the circle

Now, convert the given equation in the required  form:

⇒

or,comparing it with the circle equation:

we see

So, it implies here, (h,k)  = (-2, 0) and radius r  = 3√3 units.

Hence, for the given equation of circle, radius of circle 3√3 units.

the expected value of the random variable : 0, 1 and 2
