Answer 1

@timo86m cann you help me?

Answer 2

is it 25?

Answer 3

well use distance formula but use half of it tho. like this

Answer 4

sqrt((6+2)^2+(7-1)^2) = 10

so half of that is 5
radious is 5 :)

Answer 5

(x-2)2 + (y-4)2 =5^2

Answer 6

-.- yu so smart :Dthanks!!

Answer 7

(x-2)2 + (y-4)2 =5^2

is also

(x-2)2 + (y-4)2 =25 :)

Answer 8

Answer 9
