Answer:
5
Step-by-step explanation:
The radius is a distance on a circle from the center to a point on the circle.
We have both of these points describe here in this definition. Using the distance formula will give us the radius.
[tex]\sqrt{(x \text{ difference })^2+(y \text{ difference})^2[/tex]
The difference between 1 and -3 is 1-(-3)=4.
The difference between 5 and 2 is 5-2=3.
[tex]\sqrt{4^2+3^2}[/tex]
[tex]\sqrt{16+9}[/tex]
[tex]\sqrt{25}[/tex]
[tex]5[/tex]
