Question

the circumference of two circle are in ratio 5:6 find the ratio of their area area ​

Answer 1

Step-by-step explanation:   Heya User,

--> Let the circles have diameters, ummm, '2a' and '2b' 

--> Their circumferences --> 2πa , 2πb

--> Given, the ratio of diameters = 5 : 6

--> However, this is ---> 2a : 2b = 5 : 6

--> A common ratio to both expressions: π  ---> 2πa : 2πb = 5 : 6 

-->This implies that Ratio of Circumference of both circles = 5 : 6

___________________________________________________________________

Anyways, for such a question :->

--> Ratio [ Circumference ] = Ratio [ Radius ] = Ratio [ Diameter ]

--> Ratio [ Area ] = { Ratio [ Radius ] }²   

--> The above holds for all circles .. ☺xD
