Answer 1

here is answer....hope it helps

Answer 2

Answer:

3:4

Step-by-step explanation:

The ratio of the radii of two wheels in 3:4.

Let the ratio be x

So radii of two wheels are 3x and 4x

Circumference = 2πr

So, circumference of wheel of radius 3x = 2π(3x)=6xπ

So, circumference of wheel of radius 4x = 2π(4x)=8xπ

The ratio of their circumference= 6xπ/8xπ = 3/4

Hence  the ratio of their circumference is 3:4
