The center of circle q has coordinates (3,-2) of circle q passes through r(7,1) what is the length of its diameter? (geometry)

the distance between the center and any point on the circle is radius. double that and you get the diameter since diameter is doubled radius.

by distane formula, the radius is

sqrt( (x2-x1)^2 + (y2-y1)^2 ) = sqrt( (3-7)^2 + (-2 -1)^2) = sqrt(25) = 5

the diamter is 10

1. is 4 and 2. is 3

step-by-step explanation:

so if you look at the first one you see that 1 is to 4 and 2 is to 8 and so on, so you can see for every 1 there is a times 4 so if it were 3 then it would be 3*4 and it is 12

for number 2 it is 3 because 1 is to 3 and 2 is to 6 so for every 1 there is 3 so if it were 3 then there would be 3*3 = 9

this answer is !
