Question

Last question of my homework, I don't know what to do.
Find radius with endpoints (8,5) (10,11)
I found mid-point to be (9,8)

Answer 1

PLEASE HELP

Answer 2

distance formula

Answer 3

Distance between points (x1,y1) and (x2,y2) is
\(\huge d=\sqrt{(x_1-x_2)^2+(y_1-y_2)^2}\)

Answer 4

well i got sqrt(40) when I used the distance formula and that said it was the diameter

Answer 5

thats will give diameter

Answer 6

I don't know what half of sqrt(40) comes to be

Answer 7

radius is half of diameter

Answer 8

ok
sqrt (40) = sqrt 4 sqrt 10

Answer 9

I tried to use a decimal (3.16) and I can't use decimals with webwork so i put in fraction (79/something) and it said it was wrong

Answer 10

sqrt 4 = 2

so sqrt 40 = 2 sqrt 10

and radius = half of that = sqrt 10

Answer 11

so in standard form sqrt(10) would be sqrt(40)?

Answer 12

oh nvm just 10

Answer 13

okay i see now thank you!!

Answer 14

welcome ^_^
