Respuesta :

distance between 2 points (radius)
= sqrt( (7-2)^2 + (2-3)^2 ) = sqrt(26)

Answer:

Length of the radius of a circle = [tex]\sqrt{26}[/tex]

Step-by-step explanation:

a circle with a center at 2 + 3i and a point on the circle at 7 + 2i

To find the length of the radius, find the distance between the center and a point on the circle

center is 2+3i that is (2,3)

point is 7+2i that is (7,2)

distance formula is [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Plug in the values in the formula

Distance=[tex]\sqrt{(7-2)^2+(2-3)^2}[/tex]

Distance=[tex]\sqrt{(5)^2+(-1)^2}[/tex]

Distance=[tex]\sqrt{(26}[/tex]

Length of the radius of a circle = [tex]\sqrt{26}[/tex]
