the ratio of their circumferences?
(2)
​

Answer 1

Answer:

2:3 because

its a question from composite maths class 7

Answer 2

Answer:

Step-by-step explanation:

WKT

Formula of circumference of a circle is C = 2 π r

let the Radii be r1 and r2 and circumferences be C1 and C2

Given  r1 : r2 = 2 : 3

Now

C1 : C2 = 2 π r1 : 2 π r2  = r1 : r2 = 2 : 3

Therefore the ratio of circumferences is 2 : 3
