Question

Pleaseee help its a really important test and i dont know what im doing

Answer 1

Explanation:

one circle, lets name it x, Circumference(x)=2*3.14*r= 3.14*d, where d is the diameter

C=2*11*3.14

circle y= Circumference(y)=3.14*2*4

ratio of the radii

C(x)/C(y)=(2*11*3.14)/(2*4*3.14)=11/4= 2 3/4
