Question

Ratio of radius 2:3 of two circle ,then the ratio of their circumference is

Answer 1

according to question,
       ratio of radius = 2 : 3 
     Let radii of circles are r1 and r2

                      we know,
circumference of circle = 2πr
so, ratio of circumference of circles = 2πr1 : 2πr2 
                                                         = r1 : r2  = 2 : 3
hence, ratio of circumference is same as ratio of their  radii
