If ratio of areas of circles are 4:9:25 what is the ratio of their radiii

Given that:

Area of three circles are in the ratio 4:9:25

Let the radii of the three circles be a,b and c

We know that the formula for the area of the circle is πr2

We need to find the ratio of their radii hence will take the square root of the areas of the circle

So √4:√9:√25

We get 2:3:5
The radius are in the ratio of 2:3:5
