Question

the ratio of the radii of two wheels is 3:2 Find the ratio of their circumference ​

Answer 1

2pir/2pir=2/3

4pir=6pir

pir/pir=4/6

Answer 2

Step-by-step explanation:

let the radius be 2x and 5x

the ratio of circumference of circles=2πr1/2πr2

=2π2x/2π3x

cancelling 2π both side

=2x/3x

HENCE THE RATIO OF RADIUS AND CIRCUMFERENCE ARE SAME
