Question

the ratio of the diameters of two circles is 3:4.find the ratio of their circumferences

Answer 1

I hope this will help you..

Let the diameters be 3x and 4x

Circumference of 1circle =2πr = 2π × 3x

Circumference of 2circle=2π4x=2π × 4x

Ratio =(2π × 3x)/(2π × 4x)

Ratio = 3 : 4


therefore the ratio of their circumferences is 3 : 4.

Answer 2

Step-by-step explanation:

The ratio of diameter is 3:4

We can take 3:4 has 3x and 4x

we can divide 3x with 4x

then cancel X from 3&4 then

it is 3/4 so the circumference

is 3:4
