Given:
Center of the Circle ( 3, -2)
Point (7,1)
Determine the diameter
Formula for the diameter of the circle:
d = 2r
Solution:
Find first the radius of the circle, this can be done by subtracting the center point y of the circle and radius point y of the circle.
Radius = 1 - -2
Radius = 1 + 2
Radius = 3
Diameter = 2(3)
Diameter = 6
Final answer:
Diameter = 6
