What is the midpoint of the segment below?
(3, 5)
(-6, -6)

The midpoint is (-1.5, -.5)

Step-by-step explanation:

To find the x coordinate of the midpoint, average the x coordinates of the endpoints

( 3+ -6)/2 = -3/2 = -1.5

To find the y coordinate of the midpoint, average the y coordinates of the endpoints

( 5+ -6)/2 = -1/2 = -.5

The midpoint is (-1.5, -.5)

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).
