Question

the ratio of the radii of two wheels is 3:2 .find the circumference
​

Answer 1

Answer:

3:2

Step-by-step explanation:

R1:R2=3:2

C1:C2=?

Circumfarance=2×pie×r

C1=2×pie×3

C2=2×pie×2

C1:C2=3:2

Answer 2

Step-by-step explanation:

let the radii be 3x and 2x

circumference 1 = 2π × 3x = 6πx

circumference 2 = 2π × 2x = 4πx

$\frac{circumference \: 1}{circumference \: 2} \: = \frac{6πx}{4πx} = \: \frac{3}{2}$
