The ratio of diameter of two cir
e ratio of diameter of two circle is 4:5. Find out ratio of their area​

Answer 1

Step-by-step explanation:

let the diameter be 4x and 5x respectively,

so the respective radius would be 4x/2 =2x and 5x/2,

now ratio of their area = Pi 2x square = Pi 5x/2 square

Pi and x will cancel each other

so

ratio of their area = 4:25/4

= 16:25
