Question

if the endpoints of the diameter of a cirlce are (3,1) and (6,5) find the length of the diameter

Answer 1

the length of two points comes from:
[(x1-x2)^2 + (y1-y2)^2]^0.5
now find it!

Answer 2

i didnt learn how to do this

Answer 3

the length of the diameter is the distance between (3,1) and (6,5)
ok as suggested by shining
here x1=3 y1=1 and x2=6 and y2=5
thus d =sqrt((3-6)^2 +(1-5)^2))=sqrt( 9+16)=sqrt(25) = 5 units
