Question

if the ratio of circumference of two circle is 3 : 4 calculate the ratio of their areas ​

Answer 1

Answer:

9pie:16pie..........

Answer 2

Answer:

9:16

Explanation:

Ratio of circumference =3/4

=2*pie*r/2*pie*R=3/4

:r/R=3/4

Now ratio of area =pie*r²/pie*R²

=r²/R²=(r/R)²=(3/4)=9/16
