I'm not sure how to approach this so, if someone could point me in the right direction, it'd be appreciated.

Answer 1

Answer 2

radius x =6 units
radius y = 3 units

Answer 3

and what does that tell me and how'd you find that

Answer 4

because the radius of x is direct proportional with radius of y so this mean that

x/y=6/3 =1/2 => circle y is a halfed part of circle x

hope is now understandably sure easy

Answer 5

thank you :)
