Question

.
The diameters of two silver discs are in the ratio 2: 3. What will be the ratio of their areas?​

Answer 1

Answer:

ratio is 2:3

so Area of second circle: Ratio of the area of both circles: Hence ,the ratio of areas of two circular discs are 4:9.

Answer 2

Step-by-step explanation:

the diameter of 1st circle =2x

and 2nd circle =3x

hence Area of 1st coin÷Area of 2nd coin

= π×(2x)^2÷π(3x)^2

=4:9
