Question

The ratio of the diameters of two circles is 3 : 4. Find the ratio of their circumferenc.​

Answer 1

Answer:

3:4

Step-by-step explanation:

Circumference = (22*diameter)/ 7

So,circumference is directly proportional to diameter.

Because ratio of diameter = 3:4

Therefore,ratio of circumference = 3:4

Answer 2

GIVEN

diameter of circle A=3x

diameter of circle B=4x

radius of circle A=3x/2

radius of circle B=4x/2=2x

solution:

ratio of circumference =$\frac{2\pi \: r_{1} }{2\pi r_{2}}$

=3x/4x=3:4

answer=3:4
