Question

the ratio of the radii of two wheels is 3 is to 4 what is the ratio of the circumference

Answer 1

hii!!

here's ur answer...

let the radius of the two wheels be 3x and 4x.

ratio of their circumference-2πr/2πr

=3x/4x

=3/4

ratio:-

3:4

hope this helps...!

Answer 2

Ratio of radii of two wheels = 3:4
Let radius of one wheel be 3x cm and the other be 4x cm
Circumference of radius 3x wheel = 2π3x cm
Circumference of radius 4x circle = 2π4x cm
 Ratio of their circumference = 2π3x/2π4x = 3:4
