Question

The ratio of the diameters of two circles is 3:4.find the ratio of their circumference. I want process
​

Answer 1

Answer:

hi friends

Step-by-step explanation:

area of circle = πr^2

let area of 1st circle = πr1^2

let area of 2nd circle = πr2^2

ie, πr1^2/πr2^2 = 3/4

r1^2 /r2^2 = 3/4

that is, radius of 1st circle = 3

and radius of 2nd circle = 4

so the daimeter of 1st circle = 3x2 = 6

diameter of 2nd circle = 4 x 2 = 8

so the ratio of two daimeter = 6/8= 6:8

hope this answer is helpful
