The distance from the center of a computer disc to the edge of the disc is 6 centimeters. what is the area of the compact disc? a. 113.04 b. 18.84 c. 36 d. 452.16

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)
