Question

the ratio of the radii of two wheel is 3 ratio 4 what is the ratio of their circumference​

Answer 1

Answer:

Step-by-step explanation:

3/4=2pie r1 /2 pie r2

=r1/r2

=3/4

Answer 2

Answer:

Step-by-step explanation

Let the radius be 3x and 4x

Circumference of first wheel = 2π 3x

Circumference of second wheel=2π4x

Ratios of circumference = 2π3x/2π4x

Ratios = 3/4

Ratios of circumference = 3:4
