What will be the ratio of the radius of two circle when the ratio of their area is 4:9​

Answer»

Answer:

2:3

Step-by-step EXPLANATION:

Ratio of the AREAS of two circles=4:9

Area of circle=πr²

Let the radius of circle 1 be y.

Let the radius of circle 2 be n.

Therefore,

πy²/πn²=4/9. ( π got DIVIDED.)

y²/n²=4/9

(√y²/n²)=(√4/9). (Both SIDES under root).

y/n=2/3.

Thus, ratio =2:3.
