Question

The ratio of the radii of two wheels is 6 ratio 7 .find the ratio of their circumfrencens

Answer 1

Step-by-step explanation:

Ratio of radii of two wheel =6:7

Let the radius of first wheel be r1.

Let the radius of second wheel be r2

then the ratio will be r1:r2

ratio of there circumference=

2πr1/2πr2=r1/r2=6/7=6:7

Answer 2

Step-by-step explanation:

radius ratio = 6:7

circumference of circle =

$2\pi \times r$

as radius multiple is inly one and other part is constant hence its ratio will be same as that of radius

Ratio = 6:7
