Answer:
Step-by-step explanation:
distance = square root [
+
]
where you have two points on the line
Point 1 = P1 = (x1,y1)
point 2 = P1 =(x2,y2)
I think it’s 46.3 units squared that is the answer.
An equation of circle has form

So, the center is (13;1)
Now we need to find a radius
Let's create an equation

So radius is 2


Multiply both numerator and denominator of
by the complex conjugate of the denominator, -2+9i.

Multiplication can be transformed into difference of squares using the rule:
.

By definition, i² is -1. Calculate the denominator.

Multiply complex numbers 5-3i and -2+9i in the same way as you multiply binomials.

Do the multiplications in
.

Combine the real and imaginary parts in -10+45i+6i+27.

Do the additions in
.

Divide 17+51i by 85 to get
.

The real part of
is
.
