Answer:
IF TWO VALUES ARE <u>PROPORTIONAL</u> THEY CAN BE CONNECTED IN TERMS OF k BY MAKING THEM IN A STUCTURE OF AN EQAUTION LIKE GIVEN BELOW. HERE AS THE PROPORTIONAL VALUES ARE<u> RADIUS</u> AND <u>CIRCUMFERENCE </u>WE USE THE GIVEN VALUES AND CREATE EQAUTION LIKE BELOW
r=kC
⇒WE CAN TRASNPOSE THIS TO GET
kC/r=0
⇒C/r=1/k
RECIPROCATE IT TO GET
⇒r/C=k
Maybe this will be correct answer
