The center of circle q has coordinates (3,-2) of circle q passes through r(7,1) what is the length of its diameter? (geometry)

the distance between the center and any point on the circle is radius. double that and you get the diameter since diameter is doubled radius.

by distane formula, the radius is

sqrt( (x2-x1)^2 + (y2-y1)^2 ) = sqrt( (3-7)^2 + (-2 -1)^2) = sqrt(25) = 5

the diamter is 10

1760 kilometers

step-by-step explanation:

multiply the amount of time the plane took to travel by it's speed

the arc length is found by finding the circumference of the full circle (2xpixradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).
