Answer:
use the distance formula to find the diameter of the circle. From there, you can divide the diameter in half to find the radius of the circle
Step-by-step explanation:
so... the distance formula is...
d = [tex]\sqrt{(x_{2} - x_1)^{2}+(y_2 - y_1)^{2} }[/tex]
so...you just substitute the values into the equation
d = [tex]\sqrt{(-4-4)^2 + (-3-3)^2}[/tex]
d = [tex]\sqrt{64+36}[/tex]
d = 10
so...that means the diameter is 10
to find the radius you do 10/2 because radius is half of the diameter
so the radius is 5
hope that helps...that took so long to write out
